ABSTRACT:
Shunt element for an electrochemical storage cell or a group of several parallel-connected storage cells of the alkali metal and chalcogen type, with at least one anode space for the anolyte and a cathode space for the catholyte, which spaces are separated from each other by an alkali ion-conducting solid electrolyte wall and, at least in places, are bounded by a metallic housing. The shunt element has at least two directly adjoining spaces which can be connected to each other. The first such space is filled with a metal or with a decomposable metal compound. The second such space contains the contact surfaces of at least two electrodes which are arranged at a defined distance from each other. The first electrode is additionally connected to at least one electron-conducting surface of the first space. The two electrodes can be connected to the storage cell or cells.
