▎ 摘　　要

NOVELTY - The carbon complex cathode active material comprises a carbon nanotube that includes graphene, which is compounded in the carbon black. USE - Carbon complex cathode active material for a sodium-sulfur dioxide secondary battery (Claimed). ADVANTAGE - The carbon complex cathode active material comprises a carbon nanotube that includes graphene, which is compounded in the carbon black, and hence improves the electric conductance of the cathode active material through the introduction of the carbon nanotube or graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a sodium-sulfur dioxide secondary battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a sodium-sulfur dioxide secondary battery. Sulfur dioxide base inorganic electrolyte (1) Anode (2) Cathode (3) Case (4) Sodium-sulfur dioxide secondary battery (100)
