Abstract

Electrochemical storage cell of the sodium and sulfur type 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 regions, by a metallic housing. The cathode space contains the sulfur electrode which is made of a sulfur-impregnated graphite or carbon fiber material and the cathode space is subdivided into at least two and preferably more sectors which are separated from each other at least in some regions.
