。Prior Art and Its Problems In a sodium-sulfur battery, sodium as a cathode active material and sulfur as an anode active material are separated by a solid electrolyte tube conductive to sodium ions such as β′′-alumina. It is a completely sealed secondary battery that operates under hot dust conditions of approximately 350'C. The conventional structure of this sodium-sulfur battery will be explained with reference to FIGS. 3 and 4. Figures 3 and 4
In the figure, reference numeral 1 denotes a solid electrolyte tube, and two α-alumina rings 2 at the upper end are joined with glass solder 11. 3 is a cathode cover, and 4 is an anode cover.
Heat-pressure bonding is carried out in air at a temperature of 20'C. The anode chamber in the gap between the outside of the solid electrolyte tube 1 and the inside of the battery case 6 joined to the anode lid 4 is filled with an anode impregnated with an anode conductive material such as graphite felt! The active proboscis 7 is filled with sulfur, and the cathode chamber in the solid electrolyte tube 1 is filled with sodium as the cathode active material 8 impregnated with metal fibers. This cathode chamber is sealed by a cathode lid 3, and a cathode terminal tube 9 is passed through the upper surface 10 of the cathode chamber.

腐食されて気密不良を発生させるという欠点があった。The conventional sodium-sulfur battery as described above is manufactured by bonding the solid electrolyte tube 1 and the α-alumina ring 2 with glass solder, and then heating the α-alumina ring 2 to about 600'C.
Since the cathode cover 3 and anode cover 4 are thermo-pressure bonded to the upper and lower surfaces via the aluminum layer 5, the cathode cover 3 and anode cover 4 are oxidized under this heating, and the bond strength increases due to continuous use over a long period of time. There were cases where the bonding area deteriorated and the joints peeled off. In particular, when the cathode active material 8 rises to the upper space of the cathode chamber during battery operation, the heat-pressure joint is corroded by the cathode active material 8, resulting in poor airtightness.
