ABSTRACT:
A manufacturing method of a sodium-sulfur storage battery wherein a negative cover is thermocompressively jointed to an upper surface of an alpha alumina ring which are jointed with solder glass to a solid electrolyte tube, and a positive cover is thermocompressively jointed to a lower surface of said alpha alumina ring, is characterized in that diffusion layers of chrome are provided on the surfaces of the negative and positive covers, coating layers of aluminum are provided at least on the surfaces, which are thermocompressively jointed, of the negative and positive covers, and thermocompressively jointing surfaces are thermocompressively jointed in the air with aluminum rings thereon, respectively. Said negative and positive covers may be made from stainless steel, iron or alloy of iron and nickel. Said chrome diffusion layers may be about 20.mu.-120.mu. in thickness, respectively, and said aluminum layers may be about 5.mu.-90.mu. in thickness, respectively.
