PI Solid-state Battery Separator Solid Electrolyte Separator Lithium-ion Battery High Temperature Resistant Heat Stable Polyimide

Product Overview

Xwell Research's polyimide (PI) separators are high-performance membranes designed for next-generation battery systems, including solid-state and sodium-ion batteries. With exceptional thermal stability (-160°C to 350°C) and optimized porosity (42%), these separators enable safer and more efficient energy storage solutions for research laboratories and industrial applications.

Key Specifications

Material Advantages

Extreme Temperature Performance
- Stable operation from -160°C to 350°C (surpassing conventional PP/PE separators)
- No thermal shrinkage at high temperatures
Mechanical Robustness
- Superior puncture resistance (400g) for lithium metal anode compatibility
- Balanced MD/TD tensile strength (94/64 MPa)
Electrochemical Optimization
- 42% porosity enables 5% higher electrolyte absorption vs. standard separators
- Low impedance for high-rate applications

Handling & Processing Guidelines

Pre-Treatment
- Bake at >100°C for 2-3 hours (moisture removal)
Cell Assembly
- Maintain winding tension <0.5N to prevent stretching
Electrolyte Filling
- Use 5% more electrolyte than conventional separators
Formation Protocol
- Add 2 extra charge-discharge cycles post CV/CC formation
