The separator in the battery must have chemical stability that does not react with the electrolyte and the active material. If the separator reacts with the substances in the battery, it will destroy the electrochemical working environment, and the structure of the separator will be broke and cannot provide stable ion transmission.

Separator Material

Degradation of the separator material properties can be observed as an indicator of the effect of the chemical environment of the separator. For battery safety purposes, a state-of-the-art battery separator should have the ability to shut down the battery if overheating occurs. This overheating can be caused by overcharging or abuse of the battery.
