　　2013 (the eighth) Beijing power lithium ion battery technology and industrial development international BBS and lithium ion from the Chinese academy of engineering safety engineering frontier technology seminar held in Beijing a few days ago, the Chinese and foreign experts around the safety of the lithium ion battery and development prospect of their distinctive views are put forward. 

　　Lithium ion batteries with high energy density, long cycle life, small self-discharge, no memory effect, and outstanding advantages such as green environmental protection, new energy vehicles has become the first choice for power battery, but in the process of new energy vehicle demonstration and promotion, due to the lithium ion battery safety accidents caused by there are numerous unsubstantiated reports that the battery safety has become a key problem urgently to be solved in lithium ion batteries.

乐发9　　BBS chairman, says yuhai wang, a professor at the university of Beijing institute of technology, power lithium ion battery industry has developed rapidly in our country, the specific energy, specific power batteries and new anode materials, membrane, electrolyte are research and development, as well as the improvement of battery safety aspects have made great progress, but compared with the import of the relevant performance of lithium-ion batteries still have certain gap, so difficult to meet the demand of mass marketing of new energy vehicles, this requires domestic lithium battery in the comprehensive performance of enterprises and improve performance.
