Lithium-Ion Battery Separator (2320/2325/2400/2500) – PE Separator, Ceramic-Coated (Single/Double-Side) for Li-Sulfur, Na-K-Li Batteries

Lithium-Ion Battery Separator (2320/2325/2400/2500) – PE Separator, Ceramic-Coated (Single/Double-Side) for Li-Sulfur, Na-K-Li Batteries

Product Overview

This separator is prepared by the dry process and uniaxial stretching process. The microporous structure of the film is oblong and interconnected, resulting in good conductivity. No solvents are used in the production process, making the process environmentally friendly. The longitudinal strength of the film is better than the transverse strength, and there is basically no thermal shrinkage in the transverse direction.
