Synthesis of lithium iron battery technical information
The most studied cathode material is LiCoO2, LiNiO2, LiMn2O4 and above, three kinds of laptop battery materials and derivatives, such LiNi0.8Co0.2O2, LiNil/3Co1/3Mnl/302 so.
LiCoO2 is the only large-scale commercialization of the cathode material, at present more than 90% of the commercialization of lithium-ion battery using LiCoO2 as the cathode material. LiCoO2 research is relatively mature, comprehensive performance excellent, but expensive, low-capacity, highly toxic, there are some security issues.
LiNiO2 lower cost, higher capacity, but the preparation of difficulties, material properties of consistency and reproducibility is poor, there are more serious security problems.
LiNil/3Co1/3Mnl/302 can be seen as LiNi02 and LiCoO2 solid solutions, the advantages of both LiNiO2 and LiCoO2 once been considered the most likely to replace the new LiCoO2 cathode material, but there are synthetic conditions are harsh (requires oxygen atmosphere ), security, poor, shortcomings, comprehensive performance could be improved; same time, because ThinkPad T60 with more expensive Co, and higher cost.
Spinel LiMn2O4 low cost, safety, good, but especially the high-temperature cycle performance cycle performance is poor, in the electrolyte have a certain solubility, poor storage performance.
The new ternary nickel-cobalt composite oxides of lithium manganese oxide (LiNil/3Co1/3Mnl/302) material focused on the LiCoO2, LiNiO2, LiMn2O4 and other materials of their respective advantages: cost and LiNil/3Co1/3Mnl/3O2 very, reversible capacity, structural stability, security, good, ranging between LiNi0.8Co0.2O2 and LiMn2O4, recycling performance, synthetic easy; but with more expensive Co, and higher cost.
Sino-high-capacity, high-power 40Y6797 lithium-ion batteries, the cathode material cost, high performance, security is very important. The LiCoO2, LiNiO2, LiMn2O4 cathode material and its derivatives still can not meet the requirements. Therefore, the research and development can be used for medium-capacity, high-power lithium-ion battery cathode materials become the new hot spots.
Orthogonal structure of olivine LiFePO4 cathode material has gradually become a new hotspot at home and abroad. Preliminary studies indicate that concentration of this new type of cathode material LiCoO2, LiNiO2, LiMn2O4 and its derivatives cathode material of their respective advantages: non-precious elements, low-cost raw materials, resources and greatly enriched; moderate operating voltage (3.4V); platform features is good, voltage is very smooth (can be comparable with the regulated power supply); theory, large capacity (170mAh / g); structural stability, security, excellent performance (O and P to a solid combination of strong covalent bond, and the material is difficult to decompose oxygen evolution); high-temperature performance and thermal stability, much better than the other known cathode material; cycle of good performance; charging smaller in size, and carbon anode materials with the volume when the effect of good; with most of the electrolyte system, good 40Y6799 compatibility, storage, good performance; non-toxic, in order to truly green materials. With LiCoO2, LiNiO2, LiMn2O4 and its derivatives compared with cathode material, LiFePO4 cathode material cost, high-temperature performance, safety has obvious advantages, is expected to become a high-capacity, high-power lithium-ion battery cathode material of choice. The industrialization of the material and wider application of lithium-ion batteries to reduce costs and improve battery safety, expansion of lithium-ion battery industry, the promotion of large-scale lithium-ion batteries, high-power technology of great significance, will make lithium-ion batteries at CUHK Capacity UPS, medium and large storage batteries, power tools, electric vehicle applications a reality.
However, lithium iron phosphate, there are two obvious shortcomings, first, the low electrical conductivity, resulting in poor high-rate charge and discharge performance, the actual specific capacity is low; second is accumulation of low density, resulting in lower volume than the capacity. These two shortcomings hinder the practical application of the material.
At present, people's research focus on solving the low conductivity of phosphoric acid or lithium in this area, and has made significant progress. Improvement measures taken are:
(1) to lithium iron phosphate particles within the mixed conductive carbon material or conductive metal particles, or to the FRU 92P1139 lithium iron phosphate particles coated conductive carbon materials to improve the electronic conductivity of materials.
(2) to lithium iron phosphate (1iPePO4) mixed with a small amount of impurities in the lattice of metal ions such as Mg2 +, Ti4 +, Zr4 +, Nb5 +, to replace part of the location of Li + wide so that lithium iron phosphate into the intrinsic semiconductor n type or p-type semiconductor, significantly increased the electronic conductivity of the material.
(3) to the incorporation of lithium iron phosphate impurities such as Mn2 +, Fe2 + to replace a part of the position, increasing the lattice parameters of lithium iron phosphate to improve lithium ion conductivity of the material.
(4) using sol-gel method, liquid phase synthesis method, and other new technology, reducing the grain size of the lithium iron phosphate, and even synthesis of nano-lithium iron phosphate as much as possible to shorten the distance the spread of Li +, the apparent enhanced the material The lithium ion conductivity and material utilization.
However, the accumulation of low-density FRU 92P1141 lithium iron phosphate has been the shortcomings of people's neglect and avoid, has not yet been resolved, impede the practical application of the material. Theoretical density of lithium cobalt oxide for the 5.1g/cm3, commodity drilling the tap density of lithium is generally 2.0-2.4g/cm3; while the theoretical density of lithium iron phosphate is only 3.6g/cm3, in itself than lithium cobalt oxide be much lower. To enhance conductivity, it is mixed with conductive carbon materials, but also significantly reduce the packing density of the material, making the general carbon-doped lithium iron phosphate of the tap density is only 1.0-1.2g/cm3. Such a low packing density makes the volume ratio of lithium iron phosphate capacity is much lower than that of lithium cobalt oxide, made from the battery size will be very large, not only devoid of virtue, and difficult to apply to the actual.
Therefore, improving the packing density of lithium iron phosphate and volume than the capacity of lithium iron phosphate Practical decisive. Powder particle morphology, particle size and its distribution directly affect the packing density of the material. For example, Ni (OH) 2 is used for nickel-hydrogen batteries and nickel-cadmium battery cathode material. Previously, people used sheet of Ni (OH) 2, the tap density is only 1.5-1.6g/cm3;
Currently used spherical Ni (OH) 2 of the tap density of up to 2.2-2.3g/cm3; spherical Ni (OH) 2 has largely replaced the sheet of Ni (OH) 2, significantly FRU 92P1137 improved nickel-metal hydride batteries and nickel - cadmium battery energy density. The reference laboratory of high-density spherical Ni (OH) 2 of the research results, the successful development of lithium-ion battery cathode material for high-density spherical series, including the LiCoO2, liMn2O4, LiNi0.8Co0.2O2, LiNil/3Co1/3Mnl/3O2 so. One LiCoO2, LiNi0.8Co0.2O2 the tap density, can be 2,9 g/cm3, much higher than the commercialization of such material. Research and practical applications show that not only has the accumulation of spherical high-density products, the volume ratio of the outstanding advantages of large capacity, etc., but also has excellent mobility, dispersion and processability * can be very beneficial to production of cathode materials with * pulp and the electrode film of the coating, to improve the quality of electrodes; Furthermore, compared with irregular particles, the rules easier for coating the surface of spherical particles complete, uniform, solid layer of modification, the spherical surface modification products and more hope to further improve the overall performance.
On this basis, we propose: Ball of a 02K6651 lithium-ion battery cathode materials development. Reported at home and abroad. LiFePO4 cathode material are formed by irregular particles, the packing density of powder materials and energy and lower density. Therefore, this project seeks to spherical particles of LiFePO4 material by spherical particles to increase the packing density of the material and the volume ratio of capacity; on this basis, to play a spherical surface, coated materials, easy-to-edge, and further through the surface of spherical particles modified to improve overall performance materials. In the spherical particles of LiFePO4 materials and surface modification process, the full reference, absorption, taking advantage of people in improving the conductivity of lithium iron phosphate has made outstanding achievements; the final preparation of a spherical, high bulk density, high-volume ratio capacity, high conductivity of LiFePO4 cathode material, so that it can use in medium to large capacity, high-power lithium-ion batteries, to promote the industrialization of the material.
At present, research using divalent or trivalent ferric iron salts, phosphoric acid or phosphates, ammonia as raw materials, by controlling the synthesis of high-density 02K6928 spherical crystallization technique iron phosphate precursor, and then with the lithium source, carbon source of mixed heat treatment, through the carbothermal reduction synthesis of high-density spherical carbon-doped lithium iron phosphate. The lithium iron phosphate powder material dispersed by a single spherical particle composition, particle size 5-10um, Bulk density (tap density up to "-1.8g/cm3), good fluidity and processability of good performance, the reversible capacity 140MLNg.
Pros and cons of lithium-iron battery
Lithium-iron battery by using different materials and processes, as well as stringent quality laptop battery control in varying degrees, but had a great difference. In particular, a greater difference in price. Some difference between high and low prices or even nearly twice as much.
Why is there such a large difference in Na? Also why lithium iron batteries will be so expensive good na? One difference there? How to choose?
The production of lithium-iron battery on the environment and production process requirements are more stringent, a neglect of non-performing rate of slightly will improve immediately; To reduce the price it had to lower quality standards. Because of this, some grade B or even C grade will flow to the market. As the lithium-iron battery is still a relatively new product, many buyers now do not know how to tell whether this is also, therefore, would like to provide some distinguishing characteristics of this method and the importance of the battery pack for your reference.
Lithium-iron battery is good or bad judgments, the most basic points that can be analyzed from 02K7054 the following:
1. Uniformity
Battery hardest to do is homogeneous, but the most important of the battery string is also homogeneous. If the 10 batteries strung together, there is a first to reach over-discharge protection standards, while several others are still sufficient power, then this string of battery pack that can power capacity is not the entire lower? Has been achieved with a first place is the same reasoning.
The lack of uniformity of the battery pack, without the added protection board is very easy to broken, it is easy to overcharge or over-discharge; have unprotected board battery pack can be more you use electricity capacity will also be lower. This is also a lot of batteries plant has launched production of batteries, but was not required to group string of product causes. Because to achieve uniformity in the entire manufacturing process control is to be very strict.
Simple test method: Series 4 batteries, so 1C and 3C charge-discharge, and concept of charge-discharge process of investigation, all the voltage ThinkPad A20 batteries to see if differences in lifting the situation will know. If a row 4,5 times better to do.
2. Self-discharge rate
Lithium iron battery self-discharge rate, the theoretical value should be less than 2% per month, more than this value is not a good battery. Is not a process problem is to use the material in question.
Low self-discharge rate has always been the characteristics of lithium-iron battery, if the self-discharge rate, when you install a good finished product delivered to customer sites, it had no power, and customers will feel? Furthermore, also on behalf of a lot of energy wasted.
String in the group context, it will affect the balance of battery, that is, the battery pack that can power capacity will be less and less, and that battery life will be reduced.
Simple test method: Take 10 approximately equal to the capacitance of the battery, charge saturation put it aside for a month's time after power-up, and then measure the capacitance value to calculate the self-discharge rate ThinkPad A20M. (Put it aside after recall what the amount of voltage value, than what the battery voltage changes.)
3. Charge-discharge rate (Charge C-rate)
Fast charge and discharge is actually one of lithium-iron batteries, one of the most advantageous features, because of its fast charge and discharge, and thus allowed very similar features and a super capacitor, but its super-capacitor big capacitor than several hundred times. If the charge-discharge characteristics of its fast enough, the use of lithium-iron battery is not much significance.
In general, good quality lithium-iron battery, the charging speed of the 3C (about 20 minutes charge saturation power), while the discharge rate can reach 30C. Have special requirements can attain a higher magnification of the charge and discharge. The above situation is not hurt battery life is the premise.
Simple test method: that is, in order to manufacturer's specifications can be used to test the maximum charge-discharge rate; if the testing process, ThinkPad A21M batteries heat very serious, then the quality of the batteries is not very good.
4. Cycle life
In general, the user can not be measured, and can only trust the data provided by the manufacturer, or appointed by a professional unit on behalf of the measure. Good quality lithium-iron batteries, in 3000 the use of 1C charge and discharge cycles, its electricity capacity, attenuation, will be less than 15%.
In short, the lithium iron battery to dolphin alone, the problem spots are not large; but after the series-parallel connection to use, then the features described above should pay special attention to the. Especially in the high-voltage large-capacity battery electric strings in the group, but also pay special attention to the quality of ThinkPad R60 batteries.

Because of its high energy, battery voltage high operating temperature range, long storage life, etc., has been widely used in military and civilian small appliances, such as mobile phones, portable computers, camcorders, cameras and so on, in part to replace the traditional INSPIRON 2650 batteries.
3, lithium-ion battery development prospects
Lithium-ion batteries for its unique performance advantages in portable appliances such as laptop computers, cameras, mobile communications are universally applied. At present the development of large-capacity lithium-ion batteries in electric vehicle to start a trial, expected to become the 21st century, the power of electric vehicles, one of the main driving force, and a satellite, aerospace and energy storage aspects applied.
4, the battery's basic performance
(1) the battery open circuit voltage
(2) The battery internal resistance
(3) The battery voltage
(4) The charging voltage
Charging voltage is the secondary battery charging, the external power added to the battery voltage at both ends.
The basic method of charging Youheng current charging and constant voltage charging. Generally use the constant current charging, the characteristics of the process of charging the charge current constant. As the charging progresses, the active substance was restored, the electrode reaction area is shrinking, the electrical polarization gradually 1G222 increased.
(5) Battery Capacity
Battery capacity refers to the amount of electricity from the battery to obtain, often C, said the unit, said common Ah or mAh. The electrical properties of the battery capacity is an important indicator. The battery capacity is usually divided into theoretical capacity, practical capacity and rated capacity.
The capacity of the battery capacity of the decision by the electrodes, if the electrode capacity varies depending on the capacity of the battery capacity that smaller electrodes, but by no means the sum of positive and negative capacities.
(6), the storage battery BAT3151L8 performance and life of
One of the main characteristics of chemical power sources is used to release electrical energy can be stored when not in power. The so-called secondary battery for storage performance is to maintain the ability to recharge your batteries.
For the secondary battery, battery performance measure of good or bad, when life is an important parameter. Following a secondary battery charge and discharge, is called a cycle (or have been in this cycle). At a certain charge and discharge system, the battery capacity reaches a certain specified value before the battery can withstand the charge and discharge times known as the secondary battery life cycle. Lithium-ion batteries have excellent storage performance and long cycle life.

Notebook Battery - allows you to detailed understanding of how the laptop battery
I often see the discussion of articles aimed at saving laptop battery, speaking are some tips, but this article would like to discuss laptop battery all aspects of notebook batteries, if a look and let you have half a feeling of experts, then achieve the purpose of this paper even!
Let's take a look at from the perspective of energy-saving notebook battery, as to energy conservation, it is necessary to first know how to avoid cell "aging"! Usually, due to battery internal resistance with the use of time constantly growing larger, there will be mate voltage drop in system voltage support is not sufficient, resulting in a serious shortage of electricity. Over time this will be a vicious circle, seriously affecting the battery life books. This is fortunate, and sometimes failure of your books would be the battery failure in a very short period of time, and was very nerve-racking! This failure is probably caused by batteries, this mostly occurred in the lithium battery Latitude D800 who, in fact, books like household batteries, like flashlight barrel is determined by a composition of one of the batteries, as long as one of the a failure, then it will result in the overall series, the voltage blocked, regarding the scrapping of the! Therefore, charging to use electricity, do not use industrial use of electricity, so voltage is too large, will affect the discharge curve! Start charging, do not select fast mode (BIOS setting), the battery charging by way of constant current charging, the system load current is small, to avoid CPU, hard drive, LCD power struggle between the phenomenon. Discharge, slow down and let the CPU, hard disk stops turn, transferred to the darkest the screen (or close the switch off), do not run any programs until the laptop automatically shut down in order to achieve low current discharge purposes. Also, if the market can be found on "temperature protection device," then it is the best of! It can be achieved by adjusting the overall balance is very good battery backup protection devices.
Mentioned above, a lithium battery, battery-points of several books in the end it? We take a look at the general books are divided into the Inspiron 8500 battery nickel-chromium batteries, nickel-metal hydride batteries, lithium batteries of three. Nickel-chromium batteries, battery size due to large amount of weight, size small, short life, there are disadvantages such as memory effect, the market has been abandoned. At present two kinds of lithium and nickel-metal hydride to the market mainstream, in which lithium has a small size, light weight, large capacity, low memory effect, charging time is short, etc., have been widely used by businesses. Lithium-Ion battery was divided into two kinds, one is a lithium battery, another is a lithium-ion batteries. The existence of lithium, such as burning, the bursting of insecurity has been suspended.
Subsequently improved lithium-ion batteries, in line with the safe, efficient, convenient standard, and to become market-led, When you purchase as long as the attention of: Li-ion, the logo on it. As for the nickel-metal hydride batteries, it can be said is in line with the theme of the recent 8N544 advocacy of environmental protection, primarily to its recycling proudly features! But there are also shortcomings, such as the charging time length, weight, capacity Lithium-Ion battery smaller than the disadvantage. But the more charge cycles than lithium-ion battery 400 ~ 600 times the mean, nickel-metal hydride batteries a record high of 1,200 is very attractive! In fact, the books price of the battery determines the price of books, if you can know the origin of the battery for the threshold price is good! Japan, South Korea, China and Taiwan Province of China books are produced in cells, particularly in Japan, mostly just on the price of the battery to see Taiwan Province of China is relatively cheap, the quality of Japan, South Korea is better! Capacity, units of mA / h, recorded as: mAh, mA / h leading books of life, of course, the higher the number the better! 4000mah can support 4 hours of life time, and to long life known as Inspiron 8600 Matsushita Electric, has for more than 4500mah battery capacity should pay more attention to the time of purchase!
Mentioned earlier, the books all kinds of battery charging times, the mainstream market, rechargeable lithium-ion battery is only 400 to 600 the number of times, this figure will be books for the long-term partners as their users, it is very short, if it is day to day Fortunately, the use of power supply, if the battery then lasted only a year and a half years, which means that books to replace the battery, and then, let's focus on what the price of the battery and the sale!
In discussing the battery price, we should know: Some brands of battery is bundled sales, is that books must be the same brand, such as: Samsung, Panasonic diurnal-brand. Generally speaking, books batteries sold at 1000 ~ 3000 per hour, probably about 15% of the price of books. Of course, another ultra-thin models still considered the battery! In fact, the analysis in the previous chapter, or more cost-effective nickel-metal hydride batteries, use a long time Inspiron 6400 and prices were relatively cheap, probably around 1,500 yuan, according to a conventional nickel-metal hydride battery life is 3 years. Brands naturally more expensive big brands, in particular the price of Toshiba batteries to more than 5,000 yuan, Oh, might as well be cost-effective to purchase another one books it! However, there is your truth in your quality is worthy of recognition! Sale, the warranty should be made clear within the 3-year full warranty does not include the battery, if the price calculation, accounting for 15% of the price books how the battery can be considered a large, but the disdain for the big companies, only three month warranty. If you ask for what? They will be interpreted as the number of battery recharge is constant, damage repair room for a small remote can only be changed, the warranty is only a word performance, specific meaning does not exist! Oh, hear, you will feel? In short, buddies, CAREFUL IN THE SUMMER with the bar! Power supply is more sensible!
Finally, we take a look at how more finicky battery maintenance? First use of the battery, it should be sufficient to activate the battery, also known Inspiron E1505 as wake-up battery, the new books out of the box itself has already been with 3% of the original power, which is specifically provided for factory inspection! If you are testing machine found unusual enough battery power, then you need to do is "change"! Reason is self-evident! Back to issues that are activated if it is 24 hours and there should be no half-way off the case! When the battery exhausted, you should stop using the depth of discharge 24 hours, this is the first time should do! Secondly, to prevent power too long, if used for a long time, it is recommended to power supply! There is an article mentioned "memory effect", from the literal meaning of the general type of control is used to power-up time and the like, so set the memory effect should be removed, usually lithium-ion batteries and nickel-metal hydride have this feature, set the BIOS on the line when the attention of a! Furthermore, a measure for external protection, such as anti-exposure, moisture, anti-corrosive chemical liquids, avoid contact with the battery contacts with metal objects, etc., pay attention! Soft protection, you can enter the BIOS, the abolition of the power management GD761 options, or through special software to manage, online there are many small software wizard in this area, found perhaps give some thought!
Well, this laptop battery conversation ended here, as Zatan like pulling pull the West to understand, and want to help you!

The first three need to charge laptop battery 12 hours do?
Start using the battery, the former three to be recharged for 12 hours?
This is totally unnecessary. Because the notebook laptop battery has a complete power management circuitry and charging management system, when the battery reached saturation, the control circuit will automatically switch to the circuit state, so long as full on-line, and does not mean that you can use the longer charge longer.
In order to prevent memory effect, we should run out before electric charge do?
Each charge before the pairs of notebook battery discharge is not necessary and harmful. Practice has proved that: the battery depth of discharge would unnecessarily shorten the battery life, when the battery is used about 10% when you can recharge. Of course, when the battery power is still more than 30% of the time advisable not to charge, because the memory Presario 2100(compaq 2100) effect does exist.
AC plug when the battery should win come?
Of course not! Although the lithium-ion batteries will naturally discharge the battery after a natural discharge, if there is access to power will appear repeatedly charge and discharge conditions, reducing the battery life, but this can not be won battery justification.
Now laptop power supply control circuits have this function - when the battery reached 90% (such as most HP models), or 95% before charging, while the capacity to achieve this through natural discharge time for 2 weeks a month. When the Presario 2500(compaq 2500 battery) battery is idle for a month or so to fully charge and discharge in order to maintain the battery capacity, this time you should be concerned about is the battery should "exercise their body," rather than being idle again after the recharge.
Even if the battery has "unfortunately" been re-charged, bringing the loss, it's not a long time do not drop the battery power caused much greater. Your data than your laptop battery or even your laptop are much more valuable a sudden power failure not only to your notebook computer has a injury, is unable to restore the data too late to repent of.
So, we often see what those who claim to what is used with an ultra-AA batteries compatible with the battery level what does that mean? In fact, purely a propaganda tool, Take the Sanyo to examples of each of the 18650-capacity batteries is very easy to distinguish ways of looking at the color of the battery cover to protect gas will know the capacity size. Sanyo Presario NX9010 battery assembly plants provided by the batteries to get after the matching assembly, thus matching the first (mainly the resistance of the pair) and then assembled, in this part inside the battery manufacturers and battery pack manufacturers do not distinguish between What is the so-called A + +. Then, on the market a new 2600mah batteries source of what is it? One is a real battery assembly factory inventories, that is, a certain number of the remaining tailings batteries, battery assembly plants in order to optimize the quality of the battery is generally refuse to use the residual tailings added a new batch of batteries inside the engaged in production; the second, that is, pre-production testing process, I found a variety of factors, does not fulfill the anti-2600mah batteries, but its capacity is significantly higher than the 2400mah batteries. Outside of these two batteries is a major source of sales of new 2600mah. Therefore, this so-called A + + what the stuff is completely merchants own standards, there is no basis. Moreover, the battery capacity and the English alphabetical order the contrary, B-level is the 2200mah batteries, which is frequently used Chinese-made Presario NX9000 notebook 4400MAH origin, and the price cheap and the most mature.

Laptop battery how to use a little longer?
Laptop battery is a kind of performance degradation over time of "consumables." However, if you follow the following method of operation, will greatly extend your battery laptop battery life and performance.
1. If the laptop battery for a long time not being charged, or have never been access to notebook computers, will lead the next charge time extended
2. Please use the correct notebook power adapter. Use does not match the power adapter will charge the battery can not be filled to capacity, and will display the battery information is wrong.
3. Monthly re your battery - that is, your battery is 3% or less, this will increase your battery capacity
4. If you mainly use AC power, only occasionally use the Latitude X300 battery, you can change the battery charge threshold, to increase your battery life
5. When your computer to high-intensity operations, the battery and the temperature of the system are likely to rise. In this case, there may automatically stop charging the battery in order to ensure the effectiveness and life of the battery from losing money. Once the battery to stop charging, the battery will only be reduced to the specified temperature after re-charging, but not immediately after you plug in the AC power supply charge (and, charging time may be extended)
6. Do not, under high temperature environment using a laptop computer or the battery. For example, the hot weather of the car.
7. In a cold environment, the W0465 battery performance will be temporarily reduced.
8. When the long-term separation of the battery and notebook computers to save time, set the laptop battery power reduced to 50% or less in normal use circumstances, the battery capacity over time with the following diagram below (abscissa for the year). Batteries used depends on the number of battery charge. On a single charge refers to charge the battery to reach more than 85%. Notebook power adapter are 56W and 72W are two, using the wrong power adapter can cause the battery is not enough power, so that fewer battery capacity.
The depth of discharge Occasionally, you may need to deep discharge (1-3 times) to increase your battery performance. This requires the use of the Inspiron 2000 battery 100%, then 100% charge, and we recommend that you all night (the Ya-Ya prompted :8-12 hours) charge, during which non-use of ThinkPad. The new batteries also need to charge overnight before using.
Threshold on the charge if you mainly use AC power, only occasionally use the battery, you can charge by changing the threshold to increase the battery life. To change the charging threshold, specifically refers to the percentage of reduction in the battery starts charging (default 96%), to terminate or reduce the battery charge percentage (default 100%, but do not use the existing power of the battery should be reduced, rather than 100% charge, so that can extend battery life), thereby reducing the number of Latitude LS battery charging, extending battery life.
a. the percentage of charge termination charge than the initial percentage of at least 4% higher
b. notebook computer batteries because of aging, generally charging threshold is set higher than the ideal value of 2% c. When the charge stops when the percentage is less than 100%, please right laptop battery every three months 2834T to conduct a 100% charge.
Li-ion laptop battery how should one care is correct?
Lithium-ion battery cathode material of lithium active compounds are usually composed of negative electrode is a special molecular laptop battery structure of carbon. The common major components of LiCoO2 cathode materials
Charging
Positive reaction: LiCoO2 Li1-xCoO2 + xLi + + xe -
Negative reaction: C + xLi + + xe-CLix
Battery overall reaction: LiCoO2 + C Li1-xCoO2 + CLix
Discharge, then the occurrence of the above reaction of the reverse reaction.
Charging, the battery added to the positive pole of the electric potential to force the release of compounds Li + ions, embedded negative elements arranged in lamellar structure of the carbon. Discharge, Li + ion from the lamellar structure of carbon in the escape and re-cathode combination of 92P1101 compounds. Li + movement to promote a current.
Reactive Although very simple, but in the actual industrial production, the practical problems need to be considered much more. Cathode material additives required to maintain the multiple charge-discharge activity, the negative electrode material, which needs to design the molecular structure of class in order to accommodate more Li + ions, fill in the electrolyte between the positive and negative electrodes, in addition to maintaining stability, but also need to have good electrical conductivity, reducing the battery internal resistance.
Strictly speaking, despite the capacity of lithium-ion battery degradation, but not nickel-cadmium battery memory effect. Memory effect of the principle is that crystallization, in the lithium batteries will have little reaction. Lithium-ion rechargeable batteries in many After the release of capacity will decline, its causes are complex and varied:
One is the anode and cathode material itself changes, from the molecular level, the positive and negative electrodes of lithium ion on the hole to accommodate the structure will gradually collapse, congestion, from the chemical point of view, is the active anode material is passive, side reaction occurs to form a stable the other compounds. physically cathode 92P1089 material will appear gradually falling off, etc., in short, can ultimately reduce the battery charging and discharging process of the free movement of the number of Li + ions.
Second, catalytic additives, changes in the molecular structure of the original catalytic catalytic additives will gradually change the structure, and eventually could not even play a catalytic role in the opposite.
Third, repeated charge and discharge in the electrolyte gradually variability, resistance increases. Process bad electrolyte batteries may be due to improper control of some elements faster degeneration.
Over-charging and over-discharge, lithium batteries will be positive and negative result in permanent damage, from the molecular level, intuitive understanding, over-discharge of carbon anode will lead to excessive release of lithium ion and makes it appear lamellar structure collapsed, over-charging will too hard into the negative electrode of lithium-ion go carbon structure, causing some of the lithium-ion can no longer be released. This is why Li-ion batteries are usually equipped with 92P1087 charge-discharge control circuit causes.
Not suitable for the temperature, will lead to other chemicals in the internal lithium battery that we do not want to see the reaction of the compounds, so in some lithium between the positive and negative electrodes with a protective membrane or electrolyte additives, temperature control. In the battery temperature reached a certain circumstances, the composite membrane electrolyte membrane hole closed or degeneration, increased battery internal resistance until the circuit, the battery is no longer to heat up, to ensure that the battery charging temperature is normal.
And deep charge-discharge of lithium batteries improve the actual capacity, experts clearly tell me that this is meaningless. They even said that the so-called three full charge-discharge prior to use of "activation" in their knowledge of the two Phd years, could not understand this as a need. Why do so many people, however, after the deep charge-discharge capacity of 08K8194 Battery Information label will occur where a change? Will be mentioned later.
IBM laptop with a lithium-ion battery management chip and charge control chips. Which management chip in a series of registers, there is capacity, temperature, ID, charge status, discharge frequency values. These values are a gradual change in use, said that some value in a number of non-full-full which may lead to decline in the battery nominal capacity, the battery charge time, dissatisfaction, or the use of shorter and so on.
I personally think that the use of IBM instructions in a month should be full charge-discharge a major role in the practice now is to fix these registers where the wrong values, making the battery charge control and the nominal capacity of the battery match the actual situation. If people are way to directly read out these values, combined with recharge to analyze the situation, I would like the protection of the circuit is not difficult to crack under the control of deep charge-discharge of the 08K8196 battery indicator has improved the real reason.
Charge control the main control chip, the battery charging process. ThinkPad Li-ion battery charging process is divided into two phases, constant-current fast charge phase (the battery indicator light yellow color, ***) and constant-voltage current decreasing phase (the battery indicator light was green flashes. constant-current fast charge phase, the battery voltage gradually rises to the battery's nominal voltage, and subsequently transferred under constant pressure phase control chip, the voltage will not rise in order to ensure that no over-charge, current, along with the battery rise gradually reduced to 0, and the ultimate completion of charging.
Statistics chip power consumption by recording the discharge curve (voltage, current, time) can calculate the sample battery power, this is what we read in the Battery Information inside wh. While the use of lithium in the many after-discharge curve will change, if the Chip has not been opportunity to once again read out a complete discharge curve, which is calculated out of 92P1102 electricity that is not accurate. So we need to deep charge-discharge to calibrate the battery chips.
Finally, I right battery maintenance view is:
1. No need to ensure that every time a re-release END electric charge;
2. A period of time to do a protection circuit placed under the control of deep-charge battery power to amend the statistics, but it will not improve your battery's actual capacity.
3. A long time without the battery, should be placed in the shade in order to weaken its internal self-passivation reaction speed.
4. Protection circuit is also able to monitor the battery self-discharge, long-term without the battery should be charging to a certain degree of power to prevent self-discharge of 92P1077 batteries in storage in the discharge of excessive lead to excessive damage;
In fact, there is not much to take into account the battery use of attention, in other words is taken into account is not much use. The number of times a cell can use, and perhaps more from the battery itself, differences in the manufacture of individual differences, rather than use.
Laptop batteries batteries FAQ
Li-ion battery in accordance with zoning, that is, two kinds of industrial and civil, industrial, and generally not less 18650 are generally laptop battery used for multi-polymer batteries, polymer batteries because of the shape of a good control, 18650 is a cylindrical, relatively speaking, is not good control of shape, and polymer batteries to carry light weight, so in military technology, space science and technology, oil drilling, etc. The use of polymer-based batteries, notebook batteries using polymer present as I know X300 series, and Apple and Toshiba that thin air of the machine, but also for shapes and light. Phone using a low-capacity polymer batteries, the relatively X300 battery power density of polymer batteries, but the latter's 1 / 3 cottage mobile phone battery in order to emphasize its durable, saying that there are more than 1000 amh battery capacity, the actual are not using a polymer batteries, but lithium batteries 103450 flat, X60t 8 cores used in the capacity of 103.45 thousand batteries had reached 2000mah, X41T there are also 1900MAH, therefore, the real polymer batteries, currently used in a notebook is the unit of 08K8214 energy density in the largest.
Manufacturers in the production of the same group of cells when the battery discharge test based on the performance of classification, ABCD is divided into four categories (Sanyo distinction, as this way the distinction between Sanyo and Panasonic has actually become the industry standard), A = 2000MAH , B = 2200MAH, C = 2400MAH D = 2600MAH, the battery on the distinction between marked with ABCD code, and then at the same time shielding gas in the battery cover to distinguish color (when the battery will discharge gas, the battery positive to have a protective cover, When the battery is deflated to a certain amount of time, that is soon to meet the design life of the time, the gas would be to open the lid to the top, so that the battery off road), this is the source of ABCD, as Sanyo and Panasonic's strength, this is also On the difference between the industry has become the default mode. Of course, this by the production technology limits are to stop the original 2400mah Sanyo batteries internal material composition in favor of new material formulations, therefore, the current production of 2000-2600mah Sanyo's batteries, in fact the same production line different quality products.
So, we often see what those who claim to what is used with an ultra-AA batteries compatible with the 08K8195 battery level what does that mean? In fact, purely a propaganda tool, Take the Sanyo to examples of each of the 18650-capacity batteries is very easy to distinguish ways of looking at the color of the battery cover to protect gas will know the capacity size. Sanyo battery assembly plants provided by the batteries to get after the matching assembly, thus matching the first (mainly the resistance of the pair) and then assembled, in this part inside the battery manufacturers and battery pack manufacturers do not distinguish between What is the so-called A + +. Then, on the market a new 2600mah batteries source of what is it? One is a real battery assembly factory inventories, that is, a certain number of the remaining tailings batteries, battery assembly plants in order to optimize the quality of the battery is generally refuse to use the residual tailings added a new batch of batteries inside the engaged in production; the second, that is, pre-production testing process, I found a variety of factors, does not fulfill the anti-2600mah batteries, but its capacity is significantly higher than the 2400mah batteries. Outside of these two 08K8193 batteries is a major source of sales of new 2600mah. Therefore, this so-called A + + what the stuff is completely merchants own standards, there is no basis. Moreover, the battery capacity and the English alphabetical order the contrary, B-level is the 2200mah batteries, which is frequently used Chinese-made notebook 4400MAH origin, and the price cheap and the most mature.
From the material point of view, batteries is the rare-earth + metal + precious metals, several major battery manufacturers have been imported from China Rare Earth (RE primary production in China), because of rare earth mineral is symbiotic, so even if there is another sophisticated purification techniques, each times of production materials are weak differences in the composition (mainly impurities), while the key materials - cobalt oxide also has its own characteristics, there is weak due to the radioactive cobalt oxide, and then there is the half-life, while impurities are particularly sensitive, then, each time produced batteries, made of a different origin of the rare earth materials, the quality vary, a slight difference in impurities enough to affect the lithium cobalt oxide lattice and stability, which is produced by the same group of batteries, manufacturers must be sub - capacity to identify the truth, and the same desktop machine using 08K8192 the memory, CPU frequency identification is to use the same way.

4. Protection circuit is also able to monitor the battery self-discharge, long-term without the battery should be charging to a certain degree of power to prevent self-discharge of batteries in storage in the discharge of excessive lead to excessive damage.
In fact, there is not much to take into account the battery use of attention, in other words is taken into account is not much use. The number of times a cell can use, and perhaps Omnibook XE more from the battery itself, differences in the manufacture of individual differences, rather than use. Choose a good reputation of the notebook PC brand, is undoubtedly the future long-life battery one of the guarantees. We all know that one of the advantages of lithium batteries is that you can at any time at a convenient time for the lithium-ion battery charger, rather than insisted charge after trying to run out of power. So, what is called charge cycles? A charge cycle means that the battery power from the full use of all air, and then from the empty to full charge of the process, which is not equivalent to recharge a battery. To put it simply, 600 mA Li-ion battery, the first time you charge from 0 F2024B milliamperes to 400 milliamperes, with ah, ah, the N mA; and then you charge the 150 mA, and then the N mA ; and finally re-charge 100 milliamperes, when the last charge to 50 mA, when a piece of the battery charge cycle is up. (400 +150 +50 = 600)
1 Lithium-Ion battery on the first day only half of the electricity, and then it is fully charged. If the next day also so, that is, with half of the charge, a total of two charge down, this can only be counted as one charge cycle, rather than two. So it is usually possible to go through several times to complete one cycle of charge. Each complete a charge cycle, power consumption will be reduced a little. This is why a lot of use of lithium batteries cell phones would often say: "This broken cell phones, can be bought back 4 days, and now charge a battery can only be used three half days," reasons. However, this reduction in power consumption increase is very small, high-quality battery charge cycle many times, will still retain 80% of the original capacity, a lot of lithium-powered products are still open F2024A after the use of two or three years. Of course, life of lithium to be replaced eventually.
The life of lithium is generally a charge cycle 300-500. Assumed to provide a complete discharge of electricity for the 1Q, if not consider each charge cycle after the reduction of electricity consumption, then the life of lithium in its offer, or a total of 300Q-500Q for additional power. From this we know that if each with 1 / 2 on the charge, you can charge 600-1000 times; if each with 1 / 3 on the charge, you can charge at 900-1500. And so, if the random charging, the indefinite number of times. In short, no matter how filled, a total of 300Q-500Q added into the electricity that is constant. Therefore, we can also interpret it this way: Lithium battery life and battery power on the total charge, and the number of unrelated charge. Release of deep and shallow depth charge put sufficient light for the life of the impact of lithium or less the same. Well, some MP3 manufacturers publicity, said that "a certain type MP3 using powerful lithium Omnibook XE3 batteries, rechargeable more than 1,500 times." This is purely deceive consumers ignorant.
In fact, the light put more light rechargeable lithium battery for the benefits of the product only in the power supply module for the lithium to do calibration, the only deep deep release sufficient necessary. Therefore, the use of lithium-powered products do not have to rigidly adhere to the process, all to facilitate the first, charging at any time without fear of affecting life span.
Li-ion battery maintenance:
Temperatures should not be too high
If the above specified operating temperature, ie above 35 ° C environment, the use of lithium electricity, battery power will continue to decrease, that is, the battery power will not take as long as usual. If such a temperature, but also for the device charging, it will be more damage to the battery. Even in a relatively hot environment, storage batteries, the 346970-001 battery will be the inevitable result of the quality of the corresponding damage. So, try to keep in proper operating temperature is beneficial to extend the life of lithium a good way.
Is too low is not good
If the low-temperature environment, namely 4 ° C following the use of lithium, the same will find the battery usage time decrease, and some mobile phones Yuanzhuanglidian the environment even at low temperatures can not be recharged electricity. But do not worry too much, this is a temporary situation, is different from the use of high-temperature environment, once the temperature rose up, the battery in the molecular heat, immediately revert to a previous HSTNN-DB02 charge.
Life is Movement
To play the largest lithium-ion battery performance, often need to use it, so that the electronic lithium battery is always in flux. If you do not often use lithium electricity, be sure to remember that a month to complete a charge cycle, lithium, do a power calibration, that is, the deep dark place on one HSTNN-UB02 charge.
How to teach a scientific and rational use of laptop battery
Advantage lies in its notebook mobility, while the battery is to provide basic mobility. Laptop batteries laptop battery in notebook computers occupy a pivotal position, which is from the notebook of the benchmarks can be seen - no matter what kind of laptop is a comparison test, MobileMark an indicator of success are very important.
Advantage lies in its notebook mobility, while the battery is to provide basic mobility. Batteries in notebook computers occupy a pivotal position, which is from the notebook of the benchmarks can be seen - no matter what kind of laptop is a comparison test, MobileMark an indicator of success are very important.
Here we will briefly explain how to scientifically and to use their own laptop batteries.
First of all, a kind of popular practice F2019 whereby the use of electricity in the long hours of work, many users will remove the laptop battery that this can extend the battery life. In fact, the use habits to ensure a good premise, remove the battery module or not on laptop battery life, and there is not much impact. For users who do not remove the battery needs to pay attention not to frequent Plug Power, which is due to appear inconspicuous short plug power supply, will generate the battery charging and discharging process, the frequent charge-discharge operation will shorten the battery life; while for the battery on the side of the users, the best time to time (about a month or so), it will be placed in the battery recharge laptop computers, so that can help keep the battery in the best condition If the F2019A battery is idle for too long can lead to reduced capacity.
Second, lithium-ion battery, battery depletion is not necessary to conduct further charge that this is because lithium-ion battery is almost no memory effect. The so-called memory effect occurs in nickel-chromium batteries or Ni-MH battery, these laptop batteries not fully discharged in the circumstances, will produce a crystallization reaction, resulting in a temporary decrease battery capacity, if you want to eliminate this memory effect, can be done several times the battery fully charge and discharge cycles, there is likely to come back to save the battery.
Another issue requiring attention is the F2019B use of the environment, although the mobile computing will encounter a variety of environment, but at room temperature to ensure the use of battery life, or there are certain advantages, too cold ambient temperature on overheating notebook computers will be harm. In addition, when using a transformer operation, the power supply from outside will only support the system operation, while charging the battery, so that the charging process of charging more than shut down state operations slower, if you want to fast-charging, better carried out in the off state.
Some users complain that some laptop battery capacity display built-in reliability is not high, in fact, these products there is a special calculation of OmniBook 6000 battery capacity chips. In general, the percentage of notebook computer batteries in the display still has a certain credibility, and should be noted that from time to time, it is best to do the battery calibration operation to correct the calculation of battery capacity chips may have errors. Calibration can be performed through two methods: unplug the external power supply, turn off power management in power-saving mode, and discharge on their own notebook computers to shutdown; the use of BIOS or in random calibration provided by F1739A the related software.
To share with dell laptop battery maintenance guide
Laptop Battery Maintenance Guide
The battery is a consumable and has a limited life span, most manufacturers F2299A warranty for the laptop battery time ranging from three months to one year, Dell is to follow industry standards to provide one-year limited warranty. For the battery, the correct use and proper storage, is the ability to significantly extend the battery life of notebook computers.
1, the battery used in a few attention points.
1. Why use an external power supply, you can win without the battery?
(1) The motherboard has a chip to prevent overcharging. When the battery charge to 100%, the charge control chips (FET) will stop charging the F3172A battery. We do not have to worry about damage to the battery.
(2) The battery connections to avoid the BIOS information is lost.
(3) to prevent a sudden power loss of data.
2. To prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with metal objects touch the battery short-circuit, etc. happen.
3. A long time without notebook computers, how to preserve the battery?
We will face a period of time does not use a notebook, the battery should be full of electricity saved, or the need to put end to save electricity?
Optical long-term preservation Pavilion ZT1000 would put batteries lose their activity, and even lead to the control circuit protection self-locking can not re-use, full of electricity will bring long-term preservation security risks, the best preservation method is to use to about 40% of capacity and then save the in a cool dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, best to take the battery out every month to use them once, both to ensure the battery a good state of preservation, but also alienating the loss of damage to the battery power completely.
How do I see Dell battery power consumption? (In D610 battery as an example)
Remove the battery, according to the battery symbol, you can see five of the battery status light. Two consecutive bright, representing 40% of the Pavilion XZ200 electricity. On behalf of the whole light power is sufficient, if the 135 bright, that is, the battery is damaged.
Second, how to extend laptop battery as much as possible working time?
(1) reduce the screen brightness. How to adjust the brightness of the use of laptop batteries, boot press F2, enter BIOS to adjust the Video in the Brightness item.
Or use fn + down / up key combination to Pavilion ZT1100 quickly adjust the brightness.
Specific old BIOS please refer to:
http://support1.ap.dell.com/cn/zh/forum/thread.asp?fid=25&tid=45151
(2) Open the CPU speedstep feature, you can significantly extend battery run-time; Cpu's speedstep function of BIOS is enabled by default. When using batteries, cpu will automatically down-to use, in order to achieve energy-saving purposes. If not enabled, please switch on press F2, enter BIOS found in Performance, is set Speedstep Enable to Enabled. (Old BIOS is the Alt + P to the sixth page, modify the intel speedstep)
(3) The use of standby, sleep and other functions. As a long time without a computer, allowing notebook standby or hibernate, saving electricity Omnibook XT1000 also extended the life of notebook computers. (Tips: Make sure video card drivers installed successfully, the power management options can be set.)
In the WINDOWS proceedings against power management settings, we generally can be set to "Portable / Laptop" (Portable / Laptop).
At the same time suggest that you will use the notebook computer batteries, turn off the monitor wait time is set to 5 minutes, so that when we do not operate within a certain period of time laptops, it will direct black state, so other than the screen saver is running to be more provinces electricity.
(4) When using the laptop battery as far as possible off the Omnibook XT1500 wireless, Bluetooth and infrared terminal
