▎ 摘　　要

NOVELTY - An alkali metal-carbonaceous material comprises metal, metal oxides, or metal salts, and carbon materials. The metal is chosen from manganese, iron, cobalt, nickel, copper, zinc, molybdenum, tungsten, vanadium, zirconium, tin, antimony, indium, and bismuth. The metal oxide is chosen from ferric oxide, iron(II, III) oxide, cobalt tetroxide, cobalt oxide, nickel oxide, manganese dioxide, trimanganese tetroxide, manganese oxide, vanadium dioxide, vanadium pentoxide, molybdenum dioxide, zinc oxide, and zirconium dioxide. The metal salt is chosen from cobalt nitrate, nickel nitrate, iron nitrate, cobalt chloride, nickel chloride, iron chloride, iron sulfate, cobalt(II) acetate, and nickel(II) acetate. USE - Alkali metal-carbonaceous material used as positive electrode material for alkali metal-sulfur battery (all claimed) e.g. lithium-sulfur secondary battery. ADVANTAGE - The alkali metal-carbonaceous material provides battery having improved stability, battery capacity, and charging and discharging characteristics. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) an alkali metal-positive electrode material, which comprises sulfur and the carbonaceous material; (2) manufacture of the carbonaceous material, which involves mixing metal, metal oxides, or metal salts and carbon materials in water or solution, heating to 300 degrees C, and drying; and (3) manufacture of the positive electrode material, which involves suspending the carbonaceous material and sulfur powder in a solvent, and heating the resulting suspension to remove the solvent. DESCRIPTION OF DRAWING(S) - The drawing shows a side sectional view of the alkali metal-sulfur battery. (Drawing includes non-English language text) Lithium-sulfur secondary battery (1) Positive electrode (10) Negative electrode (12) Electrolyte (14) Separator (16) Positive electrode current collector (18)
