Details

This product is a 25 μm polypropylene (PP) separator membrane designed for lithium-ion battery research and experimental use. Manufactured via a dry stretching process, it features a consistent pore structure, strong chemical resistance to acids, alkalis, and common electrolytes, along with high thermal stability. The separator offers zero transverse shrinkage, which improves dimensional integrity at elevated temperatures and helps reduce the risk of internal short circuits. Its oxidation resistance supports stable cycling and trickle charge performance. Available as standard rolls (100 mm wide, 10 m or 330 m lengths) or pre-cut discs (φ18 mm), it is well suited for coin cell assembly and small-scale prototype testing in energy material development.

Model: 2500

Small Roll: Thickness 25um*Width 100mm*Length 10m/roll

Big Roll: Thickness 25um*Width 100mm*Length 330m/roll

This product's small roll is not original packaging, it is manually divided from the big roll, mainly to meet customers' small-scale experimental use. Customers who mind, please do not place an order.

Single layer 25um PP membrane characteristics:

Produced by dry stretching process

Excellent acid, alkali, and most chemical resistance

Consistent pore structure with high chemical and thermal stability

Suitable for various battery applications

Excellent oxidation resistance ensures excellent cycle and trickle charge performance

Zero shrinkage in the transverse (TD) direction reduces internal short circuit and improves high temperature dimensional integrity

Note: Customized separator discs require a minimum order of 10000 pieces, and the mold cost will be charged separately at 200 yuan.
