Lithium battery separator: The product uses polyolefins (PP/PE) as the main raw material, and is produced through processes such as melt extrusion of the base film, heat treatment, multi-layer composite, stretching into pores, layering, and slitting. The product has characteristics such as uniform pore distribution, small shrinkage ratio, and high puncture strength, and has innovation in controlling the crystallization speed and crystal form of the separator. We mainly produce lithium-ion battery separators with a thickness of 12-40 microns and different specifications. Our products are widely used in new energy vehicle power lithium-ion batteries, energy storage lithium-ion batteries, and digital lithium-ion batteries.
