Product Detail

Polyimide PI Separator for Solid-state Battery 

High-Temperature Resistant Thermally Stable NCM811 PI Separator Material


SPECIFICATIONS(TOB-PIP40-1, TOB-PIP40-10)

Features

1. High-temperature resistance: Exceptional safety, with a decomposition temperature up to 530°C, non-melting, and no distinct melting point.

2. Stable properties: Physical cross-linking between fibers forms a rigid support structure. The structure remains stable even after gel electrolyte filling. Under abnormal conditions such as needle puncture, the battery is ensured not to combust or explode, significantly enhancing safety.

3. High porosity: Tunable 3D microporous structure, suitable for diverse applications and compatible with different battery system configurations.
