Abstract
Electrochemical storage cell based on sodium and sulfur with an anode space and a cathode space which are separated from each other by a solid electrolyte and are bounded at least in some places by a metallic housing, and a sulfur electrode formed of a fiber-like material impregnated with sulfur arranged within the cathode space. An auxiliary substance which decomposes during charging of the cell to produce ternary sodium sulfide is arranged in the cathode space at least in the boundary regions between the solid electrolyte and the sulfur electrode.
