6 FAQs about [Types of battery separators]

What is a battery separator?

A battery separator is a polymeric membrane placed between the positively charged anode and negatively charged cathode to prevent an electrical short circuit. The separator is a microporous layer that is moistened by the electrolyte that acts as a catalyst to increases the movement of ions from one electrode to the other electrode.

What are the different types of battery separators?

Most common type of separators are polymeric porous membranes, made of polyolefin, such as polyethylene (PE), polypropylene (PP) or their combination . To improve the thermal performances of the battery, ceramic-coated PE or PP and non-woven separators have emerged.
