ABSTRACT:
The present disclosure describes a sodium-sulfur storage battery comprising a sodium-ion conductive solid electrolyte tube; a positive electroconductive material consisting of graphite felt or carbon felt, and a metal sulfide layer disposed between the solid electrolyte tube and the positive electro-conductive material. Said metal sulfide layer may be sulfurated metal such as aluminum, nickel, copper, iron, tin, zinc, lead, magnesium and chrome. A metal member may be disposed between the solid electrolyte tube and the positive electroconductive material to form said metal sulfide layer by a sulfurated part formed at least at the surface of said metal member.
