NOVELTY - A lithium cobalt oxide modified macroporous carbon sulfur positive electrode material manufacturing method involves mixing water soluble monosaccharide or polysaccharide solution and thiourea solution with deionized water to obtain mixed solution. The mixed solution is subjected to polymerization to obtain thiourea-sugar resin, which is added with hydrophilic nano calcium carbonate and nano-lithium cobalt oxide and stirring to form suspension. The suspension is spray-dried and heated to obtain a carbonized product. The product is washed with hydrochloric acid and deionized water, heated and dried.    USE - Method for manufacturing a lithium cobalt oxide modified macroporous carbon sulfur positive electrode material that is utilized for manufacturing lithium-sulfur battery (claimed).    ADVANTAGE - The method enables manufacturing the positive electrode material with improved efficiency, electrical conductivity, capacity, performance and stability.    DETAILED DESCRIPTION - A lithium cobalt oxide modified macroporous carbon sulfur positive electrode material manufacturing method involves mixing water soluble monosaccharide or polysaccharide solution and thiourea solution with deionized water at a molar ratio of 1:1:10 to obtain mixed solution. The mixed solution is subjected to polymerization at 90 degrees C for 30 minutes to obtain thiourea-sugar resin. The thiourea-sugar resin is added with hydrophilic nano carbon and nano-lithium cobalt oxide at a mass ratio of 1:1:0.1:0.5 and stirring uniformly to form suspension. The suspension is spray-dried and heated in a tubular furnace at 200-700 degrees C for 2-4 hours under nitrogen protection to obtain a carbonized product. The carbonized product is washed with 5 wt.% hydrochloric acid, and deionized water, heated and dried at 120 degrees C for 4 hours to obtain lithium cobalt oxide modified sulfur macroporous carbon as a finished product, where the nano-lithium cobalt oxide is prepared by dissolving 2.4 g lithium hydroxide monohydrate and 29.1 g cobalt nitrate hexahydrate in 10 ml deionized water, adding 1000 g/mol polyethylene glycol, stirring and dissolving, spray-drying the resultant product, sintering at 700 degrees C for 4 hours, ball-milling at 1000 rpm for 2 hours to obtain the nano-lithium cobalt oxide. INDEPENDENT CLAIMS are also included for the following:    (1) a lithium-sulfur battery    (2) a method for manufacturing a lithium-sulfur battery.
