SODIUM-SULFUR BATTERY

PROBLEM TO BE SOLVED: To provide a structure of a sodium-sulfur battery suitably used for a power storing device, a power source for emergency, an uninterrupted power source, an electric automobile or the like. SOLUTION: The sodium-sulfur battery stores a positive electrode activator 14 composed of sulfur and/or sodium polysulfide in a positive electrode chamber 5 composed of an outside of a solid electrolyte bag tube 1 and a positive electrode container 3. Either a positive electrode activator-free filling material 16' arranged in contact with a cylindrical metal member 3' with a flange and the solid electrolyte bag tube, or a positive electrode activator filling material 16 arranged in contact with a cylindrical metal member with a flange and the solid electrolyte bag tube located distant from an insulation material 6, is installed, and the solid electrolyte bag tube is laid in a lateral direction.
