The material uses a polymer called polyketone to manufacture water treatment materials and staple fibers for mattress covers. Our company will use a polymer called polyketone as a separator material.
This polymer generally has excellent abrasion resistance, which is 14 times more resistant than the POM used in contributing parts, and has superior chemical resistance to various organic solvents and weak acid bases compared to PA66.

It is possible to achieve complete localization compared to PVDF, which is currently produced domestically and is imported entirely as a raw material, and we plan to expand it to existing secondary batteries as well.
