People’s Political Consultative Conference, Beijing, some members of the CST yesterday (May 7) to Beiqi Futian Automobile inspection the development of new energy sources, some members suggested that the development of electric vehicle batteries at the beginning of the unification of standards for the future establishment of a “plus power plants,” lay the foundation for .
In the inspection process, the Foton-related person in charge of a pure electric car, the price of bicycles in the 60,000 to 70,000 yuan, while supporting the battery will be 90,000 yuan, the price of vehicles to reach 14 million to 160,000 yuan. At the same time, continuing up to 150 km mileage, but an electrical charge can be filled to six hours, two hours to charge 80%.
At present, China is still in the new energy automotive industry from the R & D to promote the use of the stage, FAW, Dongfeng, Chang’an, Chery, Beijing Auto, Geely, Brilliance and other vehicles in almost all enterprises in all the new energy vehicles R & D, batteries, motor companies, such as a large number of key components.
According to the Department of Public Works letter dated statistics, at present, 27 enterprises in China have been issued, including 76 kinds of hybrid electric, pure electric, fuel cell and other new energy cars, passenger cars. And rely on the Ministry of Science and Technology “10 City 1000″ project will be driven each year more than 10,000 new car demand for energy.
It was suggested that the state should introduce new policies to promote the development of new energy vehicles, can concentrate superior force Beijing to take part in research and development of new energy vehicles, and in new energy research and development process of vehicles, in addition to concerns about its technical content, but also attention to its designs and the effectiveness of human-computer studies. “R & D of new energy in the car directly on the high-end station, the road of China Automotive must go the road of development by leaps and bounds, the bounds must be technically and bounds.” There is a suggestion.
The existence of electric vehicles for the current price is high, the relative inconvenience to the issue of charging, it was suggested that the electric vehicles and battery electric vehicles should be separated from development, automobile production factories vehicles, battery manufacturing plant is the production of standard battery, and the establishment of additional power plants, increase can be as filling as the “batteries” to promote the development of electric vehicles, and to avoid common cause can not be due to battery replacement costs, costs of environmental protection issues.

  Lithium-ion battery at present by the liquid lithium-ion battery (LIB) and lithium-ion polymer battery (PLB) two categories. Among them, the liquid lithium-ion battery is the Li + embedded compound is positive, the secondary battery anode. LiCoO2 cathode or the use of lithium compounds LiMn2O4, negative use of lithium - carbon intercalation compounds.
Lithium-ion batteries due to high voltage, small size, light weight, high energy, no memory effect and pollution-free, self-discharge of small, long cycle life and is ideal for development in the 21st century energy. Lithium-ion batteries for its unique performance advantages in portable appliances such as notebook computers, camcorders, mobile communication has been widely used. At present, the development of large-capacity lithium-ion batteries for electric vehicles in the middle of the trial, expected to be 21 electric vehicles, one of the main power supply, and in satellites, aerospace and energy storage applications received. Its future is very bright market prospects.
Which contains the main battery business enterprises related to the listing: CITIC Guoan, Jiangsu Guotai Tibet mining,Shasha stock , China Baoan,Fousu stock , dinghy shares Keli far, the battery Desai, TCl Group.

Showa Denko, Japan announced that the large lithium-ion rechargeable battery with graphite anode materials “SCMG (Shape-Controlled-Micro-Graphite)” to develop successful, and have started selling. At home and abroad due to the large number of electric vehicles, lithium-ion rechargeable batteries have decided to adopt, so the sale has already begun.
Showa Denko business Omachi (Omachi City, Nagano Prefecture) from the current capacity of 1000 tons / year by 2012 will be raised to 3000 tons / year. Part of the current has begun to increase production capacity, such as improvements to the business of the special high-temperature graphite furnace and an additional powder processing equipment. Is expected to be completed in 09 years. The company also plans to later in 2010 as the demand for investment. 2009 ~ 2012 is expected to enhance the capacity of the equipment SCMG a total investment of about 20 billion yen. Showa Denko plans in 2012 will include SCMG including lithium-ion rechargeable battery using carbon material to expand sales to 80 billion yen.
SCMG is to use the company’s self-developed technology will be carbon powder processing of raw materials processed into the best shape, and then a special high-temperature graphite furnace for heat treatment of the anode materials made of. As a result of improved lithium-ion rechargeable battery discharge characteristics and the rapid life cycle, so battery life may be extended. R & D department for use in lithium-ion rechargeable battery auxiliaries conductive carbon nanotubes “VGCF” nurture the process of the lithium-ion rechargeable battery technology evaluation, and in the man-made graphite electrode business, the accumulation of high-temperature graphitization of the autonomy of technological development by .
