Electric vehicle batteries and six major issues facing the industry exams
Electric vehicles to be more widely promote the use of its main difficulty is that high-performance power source technology has not been effectively resolved, existing products can not meet the car on battery life, power and other performance requirements.
Currently, the battery products generally face the following problems:
Battery safety can not be guaranteed. Currently small and medium-capacity lithium-ion battery industry has been very successful, but high-capacity, high-power lithium-ion battery safety problems are not effectively addressed. The battery capacity is greater, the harm caused by out of control once it gets.
Battery capacity is limited, failure to achieve a breakthrough. Currently on the market use of electric vehicles on a single charge of driving range is usually 100km ~ 300km, and it also needs to maintain proper speed and has good battery conditioning system can be guaranteed, but the vast majority of electric vehicle under normal driving environment driving range is only 50km ~ 100km.
Battery cycle life is short. Ordinary battery charge and discharge times of only 300 to 400, even if the good performance of the battery charge and discharge times, but also 700 to 900 times, 200 times per year calculated discharge, a battery life of up to 4 years, compared with the life of automobile fuel than too short.
Battery quality and size constraints. Outside the existing size of battery electric vehicles generally achieve 550L. When such a large volume of batteries used on the family car, the car is bound to squeeze the luggage compartment. Existing battery electric vehicles are not used enough energy in storage to maintain the premise of reasonable size and quality.
Batteries are expensive. Electric car batteries cost about $ 100 / kwh, and some even as high as $ 350 / kwh, the cost is too high, users unbearable.
Environmental pollution. Battery currently used primarily for lead-acid battery, nickel metal hydride batteries, nickel cadmium batteries. Raw materials from mining to production, to waste after processing, will pollute the environment.
In addition to these six problems, the electric car battery industry is also facing exams. In China, Xianyang power grams of energy Co., Ltd., Guangzhou Great Power Battery Co., Ltd., Tianjin Lishen Battery Co., Ltd., Dongguan ATL (new energy) Electronic Technology Co., Ltd., Taiwan's Aerospace Industrial Development Corporation has successfully developed a number so small lithium-ion battery, but high-capacity, high-power lithium iron phosphate battery technology development has not been successful.
Overall, good prospects for the development of battery, but the market is still low, take time away from the real industry. Moreover, the battery business to really bigger and stronger, but also to withstand the industrial scale, large-scale R & D investment and foreign giants squeeze test.
Qingling Group and the Harbin Institute of Technology research and development of lithium iron phosphate production in Qingdao
April 17, 2010, a total investment of 300 million yuan to support 863 countries to encourage projects - Qingdao macro-resistant settled in New Energy Technology Co., Ltd. Jimo City, Shandong Province, Qingdao Garment Industrial base. The project is supporting the production of electric vehicles by the Henan Qingling Group and Harbin Engineering University R & D of lithium iron phosphate power car battery, to solve the problem of exhaust pollution.
It is understood that the lithium iron phosphate is a high-tech, pollution-free energy saving products. This class project is to encourage countries to support 863 projects, are two of the ten major revitalization of this industrial policy clearly encouraged to support the industry, in line with today's low-carbon economic development, broad market and long-term development prospects. The project was formally put into production, annual output value is expected to reach 300 million yuan, profits and taxes 30 million yuan, resettlement of more than 800 workers, will promote new energy and Jimo the rapid development of high-tech industry, led the rise on the upstream and downstream businesses, the economy of Jimo development of great significance.
Henan Qingling Group is a large comprehensive enterprise group, and now has five branches, involving packaging materials, tools, production, real estate, pig farming, building boards, five new energy industry, with more than 30 Fortune 500 companies established long-term stable business relationship. Group total assets of 10 billion yuan, a state high-tech enterprises.
Jiangsu power days and Shanghai Jiaotong University signed a cooperation agreement lithium battery powered
April 2, 2010 morning, Jiangsu power days of New Energy Technology Co., Ltd. and Shanghai Jiao Tong University on collaborative R & D project power lithium batteries and new materials at the signing ceremony. Chinese Academy of Sciences, Shanghai Jiaotong University, Professor Li Jiaming, Zhangjiagang City, Mayor Assistant Cao Yunhua attended the signing ceremony.
Jiangsu power days of New Energy Technology Co., Ltd. is an investment holding Huafang Textile Co., Ltd. a professional manufacturer of lithium iron phosphate battery technology-based companies, have achieved a 10 Ah Lithium iron phosphate battery of small batch production.
The Municipal Development and Reform Commission, Science and Technology Bureau and other departments to pull strings, Jiangsu power days and the Shanghai Jiao Tong University conducted a number of close and friendly consultation to finalize the project on the four co-signed (1, lithium iron phosphate cathode Hydrothermal synthesis and pilot production, 2, modified natural graphite anode material, 3, and more varieties of electrolyte formulation development and production, 4, automotive lithium iron phosphate power battery and system integration technology).
Cao Yunhua of Jiangsu power days of New Energy Technology Co., Ltd. and Shanghai Jiao Tong University's power lithium batteries and new materials research and development projects contracted to congratulate the company want to force day with Shanghai Jiaotong University to strengthen communication and cooperation continue to increase R & D investment, the cooperation project create the conditions for early results, said the city government and related functions will continue to support enterprises to develop scientific and technological cooperation, and promote enterprises to implement technological innovation, enterprise innovation and development to create a good environment, and invite the Shanghai Jiao Tong University in the city continue to support a wide range of technology and innovation, fight in more areas, school grounds to promote deeper cooperation to achieve mutual benefit and win-win situation.
Universal electric vehicle battery market to enter
Recently, Universal Group, announced that its wholly owned subsidiary of Ener1, and the United States on batteries and battery systems joint venture signed a framework agreement. The two sides will set up in Hangzhou, China fully automated system of batteries and battery production base, the first phase investment of 300 million U.S. dollars, is expected to the end of 2011, will be formed when the security 300 million and 4 million sets of batteries for electric vehicle battery system capacity .
