An electrochemical storage cell based on sodium and sulphur includes a metallic housing. A solid electrolyte disposed in the housing defines an anode space and a cathode space mutually separated by the solid electrolyte and outwardly bounded by the housing. A felt is disposed in the cathode space to form an electrode. The felt is impregnated with sulphur and folded at least twice. The felt has graphite or carbon fibers disposed substantially perpendicular to the longitudinal axis of the storage cell and substantially perpendicular to the surface of the solid electrolyte.
