VERFAHREN ZUR HERSTELLUNG EINER SEKUNDÄREN LITHIUM-ZELLE MIT EINEM WÄRMEEMPFINDLICHEN SCHUTZMECHANISMUS

摘要

Secondary lithium cell production comprises electrostatic powder coating of the electrodes and/or the separator with electrolyte-insoluble wax particles. Production of a secondary lithium cell, with a lithium cycling cathode, a lithium intercalating anode, a separator and a non-aqueous lithium ion conductive electrolyte, comprises electrostatic powder coating of the electrodes and/or the separator wi 0.5-2.5 mg (per cm<2> of electrode surface) of electrolyte-insoluble wax particles having a melting temperature of 50-150 degrees C and an average particle size of 6-20 microns .
