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.

Material Advantages​

  1. ​Extreme Temperature Performance​

    • Stable operation from ​​-160°C to 350°C​​ (surpassing conventional PP/PE separators)
    • No thermal shrinkage at high temperatures
  2. ​Mechanical Robustness​

    • Superior puncture resistance (​​400g​​) for lithium metal anode compatibility
    • Balanced MD/TD tensile strength (94/64 MPa)
  3. ​Electrochemical Optimization​

    • 42% porosity enables ​​5% higher electrolyte absorption​​ vs. standard separators
    • Low impedance for high-rate applications

Handling & Processing Guidelines​

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