Product Details

 About PVC-SiO2 Separator: 

The PVC-SiO2 separator that we produced has a richer pore structure, which improves the porosity of the separator, thereby effectively reducing the resistance of the separator and increasing the battery capacity.


The PVC battery separator has a porosity greater than 78%, the maximum pore diameter is less than 10 microns, the wetting speed to the electrolyte is within 2 seconds, and the resistance is only 0.0003Ω.dm2, which is one-tenth of that of ordinary separators. TRUNNANO is a trusted global PVC-SiO2 separator supplier.

Performance of PVC-SiO2 Separator

The PVC-SiO2 separator has excellent flame-retardant properties and good toughness, is not easy to be damaged during packaging, transportation and assembly of the battery, and can be processed into a bag-type separator. The PVC battery separator also has the advantages of not being easy to absorb moisture and having a long storage shelf life.
