NOVELTY - A graphene oxide is dispersed in deionized water, octadecyl trimethyl ammonium bromide cationic surfactant is added and stirred, to obtain mixed system. Ammonium thiosulfate is added in obtained mixed system, stirred and refluxed. Solid product is separated and collected, and vacuum-dried. Obtained product is heat-treated in nitrogen/hydrogen mixed gas atmosphere, and diacetylene black and polyvinylidene fluoride are mixed to form paste. Obtained paste is applied to copper foil, dried in vacuum and rolled, to obtain electrochemical lithium storage composite electrode. USE - Preparation of molybdenum sulfide graphene electrochemical lithium storage composite electrode (claimed). ADVANTAGE - The molybdenum sulfide graphene electrochemical lithium storage composite electrode is efficiently prepared with excellent cyclic characteristics, and high charge and discharge characteristics, and electrochemical lithium storage capacity, by simple method. DETAILED DESCRIPTION - A graphene oxide is ultrasonically dispersed in deionized water, octadecyl trimethyl ammonium bromide cationic surfactant having concentration of 0.02 M is added, and fully stirred, to obtain mixed system. Ammonium thiosulfate is added in the obtained mixed system, fully stirred, and 85% hydrazine hydrate is added, hydrazine hydrate is dropped, continuously stirred and heated at 95 degrees C, refluxed, reacted for 5-8 hours, and ammonium thiosulfate and oxidized graphite alkene are reduced to molybdenum sulfide and graphene. The solid product is separated and collected, and ion is washed by centrifugation, and then vacuum-dried at 100 degrees C. The obtained solid product is heat-treated in the nitrogen/hydrogen mixed gas atmosphere at 800 degrees C for 2 hours, and 80-85% molybdenum sulfide graphene electrochemical composite nanomaterial, 5-10% diacetylene black and 10% polyvinylidene fluoride are adequately mixed to form paste. The paste is uniformly applied to a copper foil as current collector, dried in vacuum and rolled, to obtain molybdenum sulfide graphene electrochemical lithium storage composite electrode. The content of oxidation graphite alkene is 26.9-80.7 mmol/l. The mass ratio of ammonium thiosulfate and graphene oxide material is 1:1-1:3. The volume ratio of mixed gas of hydrogen is 10%. The average number of molybdenum sulfide is 2-4 layers.
