NOVELTY - A lithium ion battery single-layer molybdenum disulfide/grapheme combined electrode preparing method involves dispersing graphene oxide in deionized water and adding cationic surfactant and sulfo-ammonium molybdate. Hydrazine hydrate is slowly dripped into a mixture. The sulfo-ammonium molybdate and graphene oxide are reduced into molybdenum disulfide and graphene, to obtain a solid product followed by carrying out heat treatment on nitrogen/hydrogen mixing gas, to obtain composite nanometer material. The material is mixed with graphene, acetylene black and polyvinylidene fluoride, and rolled. USE - Method for preparing lithium ion battery single-layer molybdenum disulfide/grapheme combined electrode. ADVANTAGE - The method enables preparing combined electrode with high electrochemical lithium storage specific capacity, stable circulation performance, and good high-rate charge-discharge performance, and without the usage of organic solvent, in a simple manner. DETAILED DESCRIPTION - A lithium ion battery single-layer molybdenum disulfide/grapheme combined electrode preparing method involves ultrasonically dispersing graphene oxide in deionized water, and sequentially adding cationic surfactant (26.9-60. 5 mmol/l) and sulfo-ammonium molybdate while stirring. Hydrazine hydrate is slowly dripped into the mixture and reacted at 95 degrees C under circulation reflux. The sulfo-ammonium molybdate and graphene oxide are reduced at ratio of 1: 1-1:4 into molybdenum disulfide and graphene, the mixture is centrifuged to obtain a solid product followed by washing, drying, carrying out heat treatment on a nitrogen/hydrogen mixing gas at 800?OC for 2 hours, to obtain composite nanometer material of single-layer molybdenum disulfide and the graphene. The material (80-85%), is mixed with graphene, acetylene black (5-10%) and polyvinylidene fluoride (10%) into mash, and the mash is coated on a copper foil and rolled to obtain the finished product.
