Product Details

DRY LI-ION BATTERY SEPARATOR LITHIUM ION BATTERY SEPARATOR

•All imported advanced production line.

•High purity imported PP material.

•10K level ultra-clean workshop environment.

•Thickness and blemish online detection.

•Well equipped performance testing lab.

30 years experience of stretching film manufacture

We use high purity PP material, by the optimized uniaxial stretching process and imported high-precision production line, our separator can offer better safety performance with its uniformed pore size, muti-layer structure and auto-shutdown function. it will perfectly satisfy the application for EV power battery and EESS.

High Safety

•Multilayer membrane efficiently reduce the safety hazard (crystal point, holes) found by sngle layer membrane defects;

•Hardly any TD shrinkage, low MD shrinkage;

•Perfect heat resistance and antioxidant, especially suitable for high/low viltage system;

Good Uniformity

•Using worldwide popular DRY process, insure the pore sizes uniformity and well distributed on membrance.

•The separator with multilayer lamination structure has better thickness uniformity and will improve Li-ion battery cycle life.
