Detalhes

This product is a 2325 model PP/PE/PP trilayer separator membrane developed for advanced battery and supercapacitor applications. Manufactured through a stretch process, it offers excellent chemical and acid-alkali resistance, consistent pore structure, and high thermal stability. The outer PP layers contribute to robust cycling and trickle charging performance, while the PE inner layer provides effective thermal shutdown capability. Zero transverse direction shrinkage helps reduce internal short circuits and improves dimensional integrity at elevated temperatures. With a thickness of 25 µm and width of 100 mm, it is supplied in small rolls (10 m) for laboratory-scale experiments and large rolls (250 m) for more extensive research. This separator is suitable for lithium, sodium, potassium-ion batteries, lithium-sulfur batteries, and supercapacitors, making it a versatile choice for energy material studies.

Model: 2325

Small roll: 25um thick * 100mm wide * 10m long per roll

Big roll: 25um thick * 100mm wide * 250m long per roll

The small roll of this product is not original, it is manually divided from the big roll, mainly to meet the needs of customers for small-scale experiments. Please do not place an order if you mind

Characteristics of PP/PE/PP three-layer membrane:

Produced using a stretch manufacturing process

Excellent acid, alkali, and chemical resistance

Consistent pore structure with high chemical and thermal stability

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

PP outer layer with excellent cycling and trickle charging performance

PE inner layer provides high-speed sealing ability

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