SODIUM SULFUR BATTERY, ITS USAGE AND MODULE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a sodium sulfur battery and a module using the same that can have both internal resistance reduction and large capacity. SOLUTION: In a sodium sulfur battery, a current collector 20 having a conductive layer 22 of sulfur corrosion resistance on one side or both sides of an aluminum plate 21 along the surface of a solid electrolyte bottle tube 1 is provided, and the filling density of the graphite in the positive electrode mold 10 existing between the solid electrolyte bottle tube 1 and the current collector 20 is made larger than the filling density of the graphite existing between the current collector 20 and the positive electrode container 3 side portion 31 or the graphite is not provided between the current collector 20 and the positive electrode container 3 side portion 31.
