38um Microporous Trilayer PP/PE/PP Membrance Celgard 2340 Battery Separator

38um Microporous Trilayer PP/PE/PP Membrance Celgard 2340 Battery separator

This trilayer battery separator Celgard 2340 is mainly used for primary and secondary lithium battery systems. Hydrophilic treatment is carried out on the basis of lithium battery separator, which is suitable for zinc-air, zinc-nickel and other water-based batteries. Because the diaphragm is only attached with hydrophilic groups on the surface, the hydrophilic effect of the diaphragm is not as good as that of paper, glass fiber, etc.

Features:

1. Increased thickness for strength in demanding applications

2. Uniform pore structure with high chemical and thermal stability

3. Oxidation resistance for excellent cycling and trickle charge performance

4. PE inner layer provides high-speed shutdown

5. Zero TD shrinkage reduces internal shorting and improves high-temperature dimensional stabiligy
