"Relevant departments for investigation show that at present put into use in Beijing, hybrid buses, energy-saving efficiency of only 10%, costs have increased by 50%." Chinese laptop battery Academy of Engineering, YANG Yu-sang said the development of pure electric vehicles will be more reasonable choice, lithium ion batteries and other power-type battery increasingly highlighted the importance of.
Industry has developed rapidly
Chinese Academy of Engineering Li-Quan Chen, China's lithium-ion battery industry developed rapidly, the global lithium-ion battery market has taken shape in China, Japan, Korea, the three pillars of the situation. The past two years, lithium-ion batteries used in electric bicycles has already begun and power tools. In the future, lithium-ion batteries will not only be widely used in electric vehicles, will also play a role in energy storage, lithium-ion battery market share will be further expanded. After 10 years of efforts, China has initially formed from raw materials preparation, equipment manufacturing, battery processing and export trade, as well as the development of downstream products of Presario 900 lithium battery industry chain.
In 2008, the National Li-ion battery industry output of about 200 billion yuan, of upstream and downstream value of around 50 billion yuan. In order to meet China's lithium-ion battery production in fast-growing, lithium-ion battery materials industry is also developing rapidly, basically formed a complete set of industrial clusters.
Faced with good opportunities
The United States Government attaches great importance to the development of Obama's new energy industry, especially in the last 2.4 billion investment in research and development for electric vehicles, and of which 15 million for the lithium-ion battery research and development. Many U.S. experts believe that the future of lithium-ion battery will be the same as today's oil has important strategic significance.
Driven by the 863 Program, China's lithium-ion battery technology has made great progress. China has independently developed all kinds of electric vehicles in the 2008 Beijing Olympic Games, 2009 Summer Davos Forum and other major events have been very good application. The Expo held in Shanghai next year there will be thousands of cars will be electric vehicles Presario 1700 in use, run time of up to six months, it will be related technologies for electric cars a more comprehensive examination.
In addition, the Science and Technology launched the "10 City, 1000," energy-saving and new energy vehicle demonstration and extension projects, plans to fiscal policy to encourage new energy vehicles in buses, taxis, public vehicles, and other areas of the first to promote the use, planned to use four years demonstration and extension of various types of new energy vehicles 60000, to expand sales income 100 million yuan.
China Institute of Electric Power Research Institute to a well-off, at present wind power, solar photovoltaic power generation in China developed rapidly, due to these two methods with intermittent electricity, the characteristics of volatility, a large part of energy needs to reserve The system will be able to fluctuations in input power into a stable output power, therefore a great need for storage batteries. "A wind farm configuration storage Armada E500 battery electric vehicles may exceed a few thousand vehicles need batteries." He said.
In addition, earlier this year released by the automobile industry restructuring and revitalization plan, the Government is in the field of new energy vehicles invest 100 billion, which for lithium-ion battery provides opportunities for development.
Technology needs to be improved
Although the lithium-ion battery market prospects, but industrial development there are some problems. First, the lithium-ion batteries used in material requirements to ensure that the battery is safe and has the practicality, durability, and cost under control, but China's current production of lithium-ion battery anode material properties are still to be improved. Li-Quan Chen introduction, Japan has raised the energy density of rechargeable batteries Development Goals: 2015 500Wh/kg, 2030 reached 700Wh/kg. In China, positive and negative materials currently in use combine the highest energy density can only be achieved 240Wh/kg. "In order to improve the energy density of lithium-ion batteries, must study the new chemical system." Li-Quan Chen said the government A1175 and enterprises should pay attention to technology research, if we give priority to apply for a patent abroad, we will be controlled by others. He also said that innovation in technology, lithium-ion battery life need to improve, lithium-ion battery and charging adapter of the degree of standardization need further improvement.
