Beschreibung
Zusammenfassung:	A multilayer separator is provided for insertion between the cathode and anode in lithium secondary or primary batteries, the multilayer separator comprising an electrically insulating porous membrane layer and an electroactive polymeric material layer, wherein the polymer is one that will react with any lithium dendrite formed during cycling of the battery that could otherwise penetrate the separator, thus preventing an internal short circuit of the cell.
