Description

This 2325 Trilayer Microporous Separator is designed for lithium-ion battery systems that require both electrochemical performance and enhanced safety. The separator uses a polypropylene outer layer and a polyethylene inner layer, combining mechanical integrity with a thermal shutdown function for safer cell operation. It is positioned for high-energy battery systems, especially where safety and performance stability are equally important.

Compared with single-layer polyolefin separators, this trilayer structure offers a more balanced combination of thermal resistance, dimensional stability, and internal short-circuit protection. The product is suitable for battery R&D, safety-focused cell design, pouch cell development, and cylindrical cell prototyping.

Features

  • PP/PE/PP trilayer microporous structure for safer cell design.
  • Thermal shutdown behavior from the PE inner layer.
  • PP outer layers help maintain structural integrity at elevated temperatures.
  • Zero TD shrinkage at 90°C / 1 hour.
  • Medium porosity supports stable ion transport and low self-discharge.
  • Suitable for high-energy lithium battery systems.
