Abstract

An electrochemical storage cell based on sodium and sulfur having an anode space and a cathode space, which are separated from one another by a solid electrolyte and are defined at least in some areas by a metal housing wherein the cathode space, in order to form the electrode, is filled with filamentary material of graphite or carbon that is saturated with sulfur. Between the solid electrolyte and the electrode of the cathode space, at least one intermediate film is provided, by means of which a sliding of the electrode along the surface of the solid electrolyte is assured.
