2320 Trilayer Microporous Separator for Lithium-Ion Battery Applications, 20μm PP/PE/PP

Description

This 20μm PP/PE/PP trilayer microporous separator is designed for lithium-ion battery systems that require both electrochemical performance and improved thermal safety. The separator uses a polypropylene outer layer and a polyethylene inner layer, combining structural integrity with a thermal shutdown mechanism for safer cell operation. It is suitable for high-energy cells and research environments where dimensional stability and low internal short-circuit risk are important.

Compared with single-layer polyolefin separators, this trilayer structure offers a more balanced combination of shutdown behavior, thermal resistance, and mechanical strength. The product is particularly relevant for battery R&D, pouch cell development, cylindrical cell prototyping, and safety-focused separator evaluation.

Features

• PP/PE/PP trilayer microporous structure for improved safety and performance.
• Thermal shutdown design enabled by the PE inner layer.
• Zero TD shrinkage at elevated temperature for better dimensional stability.
• Uniform pore structure supports stable ion transport.
• Medium porosity helps balance safety and energy performance.
• Suitable for high-energy lithium battery systems.
