Abstract

Electrochemical storage cell or battery based on sodium and sulfur having an anode chamber and a cathode chamber separated from each other by a dividing wall capable of conducting sodium ions, is provided with a screening electrode disposed in the chamber containing sulfur as a reactant between the dividing wall and the outer cell wall of said chamber to electrically screen the cell wall and thereby minimize corrosion of the cell wall.
