ナトリウム−金属塩化物系二次電池及びその製造方法

摘要

There are provided a sodium-metal chloride secondary battery and a method of manufacturing the same. A secondary battery that is operated at room temperature and has a more stable electrochemical characteristic is provided. The present invention provides a sodium-metal chloride secondary battery and a method of manufacturing the same. The battery includes an anode made of a sodium-containing inorganic material, an electrolytic solution containing an electrolyte (NaAlCl 4 ) and a solvent (sulfur dioxide), and a cathode including a carbon-based material in which NaCl is generated and decomposed according to an oxidation-reduction reaction of NaAlCl 4 -xSO 2 and a metal chloride (CuCl 2 ).
