Separator

A separator is a permeable membrane placed between a battery's anode and cathode. The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.

Separators are critical components in liquid electrolyte batteries. A separator generally consists of a polymeric membrane forming a microporous layer. It must be chemically and electrochemically stable with regard to the electrolyte and electrode materials and mechanically strong enough to withstand the high tension during battery construction. They are important to batteries because their structure and properties considerably affect the battery performance, including the batteries energy and power densities, cycle life, and safety.

LIBCOIN has partnered with Celgard who is recognised as the world leader in the manufacture of customised  high-performance separators for the lithium-ion battery industry. Celgard with more than 40 years of market-leading research, development, and manufacturing, deliver highly-engineered products with proven quality and performance.
