Lithium power battery was listed in the industry technology development guide

Recently, the Ministry of Industry and Information Technology issued the "Guidelines for the Development of Key Technologies for Industry (2015)". The guide has identified 205 key common technologies for priority development, including lithium-ion batteries and new energy vehicles.

Guide pointed out that the key generic technology application has basic industry, relevance, systemic, open wait for a characteristic, because of its difficult research, cycle is long, has become the industry sustainable development of our country and promote industry core competitiveness bottleneck problem, strengthen the key common technology research and development is one of the most effective way to speed up the promotion industry technology.

The following is the key generic technology development guide (2015) "in the Lithium-ion battery and the new energy automobile parts:
