Abstract
An electrochemical storage cell based on alkali metal and chalcogen with an anode space and a cathode space separated from each other by an alkali ion-conducting solid electrolyte. The cell is bounded by a metallic housing. A closure seals the top of the cell in a sealing zone. The open end of the can shaped solid electrolyte disposed in the interior of the cell is bonded by a bonding material to a ring-shaped insulating part which defines the two reactant space relative to each other in the sealing zone. In the sealing zone of the storage cell closure, the metallic housing as well as the solid electrolyte and the insulating part fastened to it are covered by a protective layer.
