This product, the PIP40 PI solid-state battery separator, is developed for advanced energy storage research, particularly in solid-state battery systems. Made from polyimide (PI) film, it offers exceptional thermal stability with a decomposition temperature of 530°C and no melting point, enhancing safety under extreme conditions like puncture or impact. Its physical structure provides a rigid support that remains stable after gel electrolyte filling, while a high porosity exceeding 90% and an intelligently adjustable 3D microporous network allow compatibility with various battery chemistries. Technical specifications include a thickness of 30±5 μm, tensile strength of at least 5 MPa in both directions, and a liquid absorption rate above 80%. This separator is applicable to all-solid-state, lithium metal, lithium-sulfur, and sodium-ion batteries, where it contributes to high voltage resistance, low interfacial impedance, resistance to dendrite penetration, and inhibition of polysulfide shuttle effects. It is not intended for traditional liquid lithium batteries.

Characteristics of PI film application in solid-state batteries

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

2. The physical adhesion between the fibers forms an effective rigid support structure, and the structure is stable after gel electrolyte filling. In abnormal use environments such as acupuncture and impact, ensure that the battery does not burn or explode, which greatly improves safety;

3. High porosity, 3D microporous structure is intelligently adjustable, suitable for a variety of application scenarios, and matches the product regulation of different battery systems
