Double-Sided Polyimide Coated PE Separator

Product: Double-Sided Polyimide (PI) Coated PE Separator (High-Temperature Resistant)
Application: Separator for High-Safety Lithium-ion Batteries
Product Overview: This separator is manufactured by coating polyimide (PI) slurry onto a polyethylene (PE) base film. It exhibits excellent high-temperature thermal dimensional stability (>200deg C) and resistance to hot needle puncture propagation, significantly enhancing the safety of lithium-ion batteries by combining the advantages of PE and PI materials.
