Functional film》 Lithium battery separator

The main function is to isolate the positive and negative electrodes to prevent battery self-discharge and bipolar short circuit. The main materials are porous polymer membranes, including dry diaphragms, ceramic coated diaphragms, and PET non-woven diaphragms.


性、孔隙度及膜厚度将互相影响离子传导度及机械强度,所以制造不同的产品必须应用不同的设计方式,如单层、双层及三层的隔离膜。 Because the safety, permeability , porosity, and membrane thickness of the diaphragm will affect the ion conductivity and mechanical strength of each other, different designs must be applied to manufacture different products, such as single-layer, double-layer and triple-layer separators.

膜,并拥有稳定量产经验,提升产品性能和质量。 Lithium battery separators for different applications can be developed for different processes and raw materials , and have stable mass production experience to improve product performance and quality.
