Japanese firm Teijin Limited has signed a technical license agreement with China’s Shanghai Energy New Materials Technology (SEMCORP) to make solvent-based coating separators for lithium-ion secondary batteries.
Teijin aims to integrate its technologies with SEMCORP’s strengths in substrate production capacity and cost competitiveness.
The agreement covers Teijin’s technologies and patents related to coating and production processes for fluorine and solvent-based coating separators.
The companies plan to explore opportunities in the automotive field, specifically the development of separators that enhance the capacity, performance, durability and safety of lithium-ion batteries for electric vehicles.
Teijin has developed two types of polyethylene-based coated separators with its proprietary technologies－one coated with a highly heat-resistant meta-aramid, and the other coated with fluorine-based compounds.
