Polymer Coated Battery Separator Film with  Polymer PVDF Coating

Tianhong corporation has advanced international production lines for Li-ion battery separator by dry and uniaxial stretching process, equipped with high precision testing instruments, using high purity PP material and advanced production technology, mainly produce Li-ion battery separator film in thickness of 12-60 microns with different specifications, which is widely used in Li-ion power batteries, Li-ion energy storage battery and Li- ion digital product battery.

We are also producing the coating separator film : 

PVDF coating separator film :

√ It can improve the interface characteristics between the separator and the electrode plate,there by increasing the hardness of the battery and enhancing safety。

√ Increase the wet-ability and retention of electrolyte.

√ Enhance the electro-chemical stability.
