Abstract
Provided is a sodium secondary battery including: an anode containing sodium; a cathode containing sulfur; a cathode electrolyte solution being in contact with the cathode and capable of conducting sodium ions into and from a solid electrolyte membrane; and a solid electrolyte separating the anode and the cathode electrolyte solution and having sodium ion conductivity. The sodium secondary battery of the present invention overcomes the problems of thermal management and heat sealing due to a high operating temperature, possessed by the existing sodium-sulfur battery or sodium-nickel chloride battery (so called, a ZEBRA battery), and may achieve high a charge and discharge mechanism characteristic.
