Abstract
Electrochemical storage cell of the alkali metal-and-chalcogen type with at least two spaces (anode and cathode space) separated by an alkali-ion-conducting solid electrolyte for receiving the reactants. The cathode space contains as catholyte at least one chalcogen or chalcogenide in dissolved or melted form, preferably sulfur or sulfides, as well as carbon- or graphite felt as the electrode material. The felt is provided with a layer that is porous, i.e., the surface of its fibers expose, in island-fashion, an alkali-ion-conducting substance which permits improved rechargeability at lower temperatures.
