MEDIUM-LOW HEAT DRIVEN SODIUM-BASED SECONDARY BATTERY AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2018/097390

A1

The present invention relates to a sodium secondary battery comprising: an anode container for accommodating sodium; a cathode container for accommodating a cathode active material and a cathode secondary electrolyte; a solid electrolyte positioned between the anode container and the cathode container and selectively moving sodium ions; and a polymer sealing layer formed along the edge of the solid electrolyte and positioned between the solid electrolyte and the anode container and between the solid electrolyte and the cathode container. Since the sodium secondary battery of the present invention uses the polymer sealing layer, an expensive bonding process and an expensive bonding facility are unnecessary, the number of parts of a single cell can be reduced, and a battery manufacturing process can be simplified.
