Feature(may vary by option.)

●Ceramic diaphragm is made of PP diaphragm as the substrate, coated with a single layer of Al2O3 material on the surface, and treated with a special process to bond tightly with the substrate.
●The coated separator film is based on the traditional PP film. The thermal stability of the separator film is improved by coating high-purity nano-alumina materials on one or both sides, with better high-temperature resistance and better liquid absorption and retention performance.
●It is mainly used in power battery and multiplier battery, which can greatly improve the safety and stability of lithium-ion battery.
