Core Functional Advantages
- Uniform Pore Structure for Efficient Ion Conduction
The wet-process manufacturing technique creates evenly distributed pores, enabling smooth lithium-ion transport between positive and negative electrodes while blocking electron flow. This optimizes battery rate performance and cycle stability. - Superior Mechanical Strength for Production Reliability
With high puncture resistance and balanced MD/TD tensile strength, the separator resists damage from electrode burrs and winding stress during battery cell assembly, reducing short-circuit risks in mass production. - Excellent Thermal Stability for Enhanced Safety
Low thermal shrinkage at 90? maintains structural integrity under mild overheating conditions, preventing direct contact between electrodes and significantly improving the battery?s safety performance during use and storage.
Application Scenarios
This PE separator roll is a versatile solution for lithium-ion battery production and R&D, ideal for the following scenarios:
- Mass production lines of consumer electronics batteries (smartphones, laptops, wearable devices)
- Electric vehicle (EV) and energy storage system (ESS) battery cell R&D and pilot-scale production
- New energy battery material performance testing and optimization experiments
- Custom lithium-ion battery manufacturing projects requiring high safety and long cycle life
Quality Compliance
- The polyethylene raw material complies with ISO 10993 chemical inertness standards, ensuring no adverse reactions with battery electrolytes.
- Mechanical performance testing adheres to ASTM D882 (tensile strength) and ASTM D726 (puncture resistance) international protocols.
- Thermal shrinkage testing meets IEC 61960 battery component safety requirements, aligning with global lithium-ion battery industry standards.
