NOVELTY - A molybdenum sulfide nanoribbon-graphene composite electrode comprises nanoribbon/graphene composite (80-85 %mass), acetylene black (5-10 %mass), and polyvinylidene fluoride (10 %mass). USE - Molybdenum sulfide nanoribbon-graphene composite electrode is used for lithium ion battery. ADVANTAGE - The molybdenum sulfide nanoribbon-graphene composite electrode is manufactured economically using simple process. The battery containing the electrode has high battery characteristics, capacity, and cycle performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of molybdenum sulfide nanoribbon-graphene composite electrode. Graphene oxide (26.8-60.5 mmol/L) is ultrasonically dispersed in deionized water, cation surface active agent (0.01-0.05M) is added to dispersed mixture, and fully stirred. The obtained mixture is added to molybdenum thiosulfate, fully stirred, hydrazine hydrate (85 %mass) is dripped to the mixture, heated at 95 degrees C, continuously stirred and reacting for 5-8 hours to reflux. The mass ratio of graphene oxide to molybdenum thiosulfate is 1:0.5-1:4. The graphene oxide and molybdenum thiosulfate are reduced to molybdenum sulfide and graphene, separated an solid product is collected. The product is washed using deionized water, and then dried at 80 degrees C. The dried product is heated at 800 degrees C for 2 hours in nitrogen/hydrogen mixed atmosphere, to obtain molybdenum sulfide nanoribbon and graphene composite material. The obtained material is mixed with acetylene black and polyvinylidene fluoride, to obtain nano-composite electrode.
