Recently, the Ministry of Science and Technology High-tech Division experts in Beijing on the "second five" national science and technology support project "lithium-ion battery with a new high-security diaphragm research and application demonstration" project acceptance. Acceptance of the project team in accordance with the "National Science and Technology Support Program Management Measures" and "National Science and Technology Support Program special funds management approach" and other relevant provisions, listened to the project leader on the implementation of the project report, review the relevant materials, the inquiry and discussion, acceptance The expert group considered that the project had completed the specified main tasks and targets and agreed to the acceptance.
Lithium - ion battery technology research breakthroughs
In this project, the lithium-ion membrane with adjustable thickness of 20-40 microns was prepared by using controlled UV cross-linked poly (aryl ether ketone). The key technology of lithium ion battery based on new high safety diaphragm was studied, and the battery system test and development platform , Carried out a battery management system of efficient energy balance technology research. Built an annual output of 30 tons of controlled UV cross-linked poly aryl ether ketone lithium-ion battery separator raw material production line, with an annual output of 1 million square meters of controlled UV cross-linked poly aryl ether ketone lithium-ion battery separator production line, the battery system in the electric Bus on the demonstration application. The acceptance group agreed to the project acceptance.
