FSPG&GELLEC Lithium Battery Separator
FSPG&GELLEC lithium battery separator is engineered for next-generation lithium-ion batteries, offering superior mechanical strength, thermal stability, and chemical resistance. Our wet-process PE base film features low thermal shrinkage (<5% at 105°C), high porosity (up to 52%), and low gas permeability (as low as 80 s/100ml). Available in thicknesses from 2μm to 25μm, GELLEC separators support high energy density and fast charging applications. With advanced coating technologies — including inorganic, organic, and composite coatings — we deliver enhanced adhesion, ion conductivity, and wettability. Trusted by CATL, BYD, LG Energy Solution, and other global leaders, GELLEC ensures safety, reliability, and performance for EV, energy storage, and consumer electronics.
GELLEC lithium battery separator is a critical component in lithium-ion batteries, physically separating anode and cathode while allowing ion transport. As a global leader in wet-process separator technology, GELLEC combines advanced R&D with intelligent manufacturing to deliver consistent, high-quality products for power and energy storage batteries.
