Abstract
Electrochemical storage cell or battery of the alkali metal and chalcogen type with at least one anode space intended for receiving the anolyte and a cathode space for receiving the catholyte. The spaces are separated from each other by an alkali-ion-conducting solid electrolyte wall, and sulfur or sulfides are filled into the cathode space. The cathode space is filled with two or more porous layers of which always at least one is ion-conducting and one is electron-conducting. At least one ion-conducting layer rests at least in regions against the solid electrolyte, and at least one electron-conducting layer rests at least in some areas against the metallic housing of the storage cell. An electron-conducting layer is adjacent to each ion-conducting layer and vice versa. At least the electron-conducting layer is impregnated with sulfur.
