The present invention discloses a manufacturing method of a sodium-sulfur storage battery comprising battery components of metallic members jointed by means of a thermocompression method to an alpha -alumina ring which is jointed to a sodium ion conductive solid electrolytic tube using solder glass. According to the invention, thicknesses of the metallic members thermocompressively jointed to upper and lower surfaces of said alpha -alumina ring is in a range from about 0.2 mm to about 0.6 mm. Plate-shaped aluminum rings are disposed between said alpha -alumina ring and said metallic members respectively and are thermocompressively jointed in air under condition of a temperature in a range from about 600 DEG to about 625 DEG C. and a pressure in a range from about 1200 to about 1600 kg/cm2. |
