Electrochemical storage cell

摘要

Electrochemical storage cell of the alkali metal and sulfur type with an anode space and a cathode space which are separated from each other by an alkali ion-conducting solid electrolyte and are bounded at least in some regions by a metallic housing. A safety insert is provided for receiving the alkali metal. The alkali metal can emerge via at least one discharge opening into a safety gap. A fusible part is arranged for closing the discharge opening within the safety insert. The part is made of an alloy which contains at least two metals of the groups IB, IIA and/or IIIA of the periodic system. A material for increasing the melting point of the alloy is arranged in the discharge opening.
