▎ 摘  要

NOVELTY - A graphene and molybdenum-sulfide nano-composite has three-dimensional structure obtained by dissolving 2-5 mg graphene, 15-35 mg molybdenum trioxide, 0.3-0.6 g urea and 30-60 mg thioacetamide in 15 ml of deionized water and 35 ml ethanol mixed solution, thermally insulating and drying the resultant product, cooling to room temperature, sedimenting the water and cleaning by ethanol, vacuum drying at 60 degrees C to obtain a compound material, and mixing the graphene with the molybdenum-sulfide nano-composite, conductive carbon and sodium carboxymethylcellulose to obtain a cathode material. USE - Graphene and molybdenum-sulfide nano-composite for manufacturing a lithium ion battery. ADVANTAGE - The graphene and molybdenum-sulfide nano-composite produces a lithium ion battery with better cycle characteristics and high capacity. DETAILED DESCRIPTION - A graphene and molybdenum-sulfide nano-composite has three-dimensional structure obtained by dissolving 2-5 mg graphene, 15-35 mg molybdenum trioxide, 0.3-0.6 g urea and 30-60 mg thioacetamide in 15 ml of deionized water and 35 ml ethanol mixed solution, thermally insulating and drying the resultant product at 200 degrees C for 18-24 hours, cooling to room temperature naturally, sedimenting the water and cleaning by ethanol, vacuum drying at 60 degrees C to obtain a compound material, and mixing the graphene with the molybdenum-sulfide nano-composite, conductive carbon and sodium carboxymethylcellulose at a mass ratio of 8:1:1 to obtain a cathode material. An INDEPENDENT CLAIM is also included for a method for preparing graphene and molybdenum-sulfide nano-composite.
