Separator (electricity)
OverviewHistoryMaterialsProductionPlacementEssential propertiesDefectsUse in Li-ion Batteries
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.
