Abstract

An electrochemical storage cell or battery with an anode space for an alkali metal as the anolyte and with a cathode space for a sulfur-containing catholyte substance, which are separated from each other by an alkali-ion-conducting solid electrolyte and are confined by a cell wall of metal, particularly of a light metal or steel. Long-life corrosion protection of the metal cell wall is provided by a protective layer by applying to at least that part of the metal cell wall in contact with the catholyte substance, a foil of corrosion-resistant material 0.01 to 0.2 mm thick by means of a conductive adhesive which retains its adhesive properties at operating temperatures.
