The coated battery separator is based on the traditional polyolefin separator. The thermal stability of the separator is improved by coating high-purity nano-alumina or boehmite and other 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.

Innovative battery technology is now more important than ever because it is the key to realizing climate-friendly electromobility across the globe. With our Next Generation Solutions, EV battery manufacturers can optimize the performance of batteries in terms of both safety and driving distance.
