Meta-Aramid Coated Separator (SEP-ARA-12), PE Base Film with Meta-Aramid Coating, High-Temperature Resistance and Anti-Oxidation for Lithium-Ion Batteries

About this item

• Aramid Coating for High-Temperature Resistance: features a meta-aramid coating on a 9 µm PE base film (total thickness ~12.5 µm), providing low density, excellent thermal stability, and outstanding oxidation resistance to enhance battery safety and fast-charging performance
• Excellent Thermal Stability: exhibits thermal shrinkage of ≤ 11.6% MD and ≤ 5.9% TD at 140°C for 1 hour, providing superior dimensional stability at elevated temperatures and effectively reducing internal short circuit risks during thermal runaway events
• High Mechanical Strength: provides MD tensile strength of ~2229 kgf/cm², TD tensile strength of ~1566 kgf/cm², and puncture resistance of ~521 gf, ensuring robust processing during cell assembly and reliable long-term cycling performance
• Good Permeability & Wettability: features air permeability of ~246 sec/100ml with excellent electrolyte wettability provided by the aramid coating, promoting rapid electrolyte infiltration, uniform ion transport, and improved battery cycle performance
• Wide Application Range: suitable for lithium-ion batteries used in 3C electronics, electric vehicles, and energy storage systems, with the meta-aramid coating improving thermal stability, fast-charging capability, and cycle life while maintaining low weight and high safety standards
