Battery Separator Film and Coating Technology

BenQ Materials’ multi-layer separator possesses a thermal shutdown mechanism at low temperature with a PP/PE/PP tri-layer structure. Through a unique formula, stretching technology and process controlling, the separator also possesses low impedance/DCIR and is able to prevent delamination and wrinkle formation after soaking in electrolytes. Our separators are suitable for high safety, high power, and long cycle life requirements for battery separator materials for automotive batteries and energy storage systems.
