Lithium Battery Separator is a kind of microporous film which main matrix is polyolefine film, it has manufactured by one-step or two-step stretching in hole craft and had ion pass-through function, in the li-ion battery it has played a role of separate positive pole and negative pole of battery to avoid short circuit. Following the development of technology of separator there has gradually derived some new types of li-ion battery separator, such as PP/PE/PP compound separator, ceramic coating separator resistance to high temperature and PVDF coating separator with high performance.

We produce complete range of lithium battery separators with various thickness and different physical properties based on customer demand.Our products have high security and excellent heat shrinkage performance,perfect anti-stretching and anti-threading,good compatibility with electrolyte and high liquid absorption rate and liquid protection rate,excellent electrochemical performance.
