Product Application

This product is a high-performance dedicated separator material for lithium-ion batteries. Relying on the excellent mechanical properties of the PE substrate and the high-temperature resistance and short-circuit prevention advantages of the double-sided Al2O3 coating, it plays a core role in lithium-ion batteries:
  • Precisely separating the positive and negative electrodes, eliminating short-circuit risks from direct contact and ensuring battery safety.
  • Optimized pore structure and air permeability enable full electrolyte penetration, accelerating lithium-ion migration and enhancing charge-discharge efficiency & rate performance.
  • Outstanding puncture/tensile strength and low thermal shrinkage boost battery structural stability and extend cycle life.
Suitable for various lithium-ion battery production scenarios (consumer electronics, power batteries, etc.).

Quality Compliance

  • Raw materials comply with ISO 10993 chemical inertness standards, no adverse reactions with Li-ion battery electrolytes.
  • Mechanical testing adheres to ASTM D882 (tensile) and ASTM D726 (puncture) international protocols.
  • Thermal shrinkage testing meets IEC 61960 battery component safety requirements.
