electrolyte is connected at its open end to a ring shaped insulator 5 the insulator 5 is made of u03b1 aluminum oxide and joined to the solid electrolyte 3 via a glass solder 6 the insulator 5 is designed so that it extends outward beyond the solid electrolyte and assumes the function of a flange the metallic housing 2 of the storage cell 1 has at its open end an inward directed flange 7 the insulator 5 is placed and supported thereon preferably a seal not shown here is also arranged between the insulator 5 and the flange 7 the interior of the solid electrolyte 3 serves as the cathode space 8 in this embodiment a cup shaped container 9 is arranged above the open end of the solid electrolyte 3 the inside diameter of the cup shaped container 9 is matched to the inside diameter of the solid electrolyte 3 the cup shaped container 9 faces with its open end the solid electrolyte 3 it is made of metal and has an outward pointing flange 10 with which it is supported on the insulator 5 the insulator 5 and the flange 10 are firmly connected to each other the cup shaped container 9 forms the supply container for the sodium polysulfide in the vicinity of the insulator 5 the solid electrolyte is provided with a cover plate 11 which separates it from the supply container 9 between the inner boundary surface of the solid electrolyte 3 and the cover plate 11 an annular empty space 12 is provided for.
