Abstract

An electrochemical storage cell is bounded by a metallic casing and has a cup-shaped solid electrolyte on the inside which separates an anode compartment from a cathode compartment. The storage cell is externally closed in a leak-proof and gas-tight manner. A closure of the cell has an additional seal with two mutually overlapping components between which an insulating ring is disposed.
