Features of PI membrane in solid-state battery applications:

1. High temperature resistance, high safety, decomposition temperature up to 530°C, no melting, no obvious melting point;

2. Physical bonding between fibers forms an effective rigid support structure, and the structure is stable after filling with gel electrolyte. Under abnormal use environments such as needle puncture and impact, the battery is guaranteed not to burn or explode, and the safety is greatly improved;

3. High porosity, 3D microporous structure is intelligently adjustable, suitable for a variety of application scenarios, matching product specifications of different battery systems
