▎ 摘　　要

NOVELTY - Reduction-oxidation graphene coated molybdenum disulfide composite material comprises three-dimensional mesoporous structure of flower-shaped sphere molybdenum sulfide/rGO composite material. The nano-sheet assembled molybdenum sulfide micro-sphere prepared by ion liquid hydrothermal method has high porosity and hollow structure, providing the edge active site and buffering the electrochemical large volume expansion. The composite material is uniform three-dimensional layered heterostructure, by space limited effect, molybdenum sulfide sphere is inhibited when growing in the interlayer of rGO, so as to increase the interlayer distance and improve the multiplying power performance of the electrode. USE - Reduction-oxidation graphene coated molybdenum disulfide composite material used for cathode of lithium ion battery. ADVANTAGE - The reduction-oxidation graphene coated molybdenum disulfide composite material increases the contact and the electrolyte and improves the mechanical stability of the electrode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for reducing graphene oxide coating molybdenum disulfide composite material, involving: a. adding sodium molybdate dihydrate and 1-butyl-3-methyl imidazole thiocyanate (BMIM) SCN in graphene solution under low speed stirring to obtain mixed solution; b. transferring the mixed solution into a hydrothermal synthesis kettle, after screwing and sealing, placing in a constant temperature electric heating oven; performing solvent thermal reaction; c. cooling hydrothermal synthesis kettle to the room temperature along with the constant temperature electric oven after reaching the solvent thermal reaction time; d. centrifuging the solid-liquid mixture after reaction, and using distilled water, repeatedly washing by ethanol for many times, placing in a vacuum drying box and fully drying under constant temperature environment to obtain solid powder; and e. putting the dried solid powder in a tubular furnace for annealing treatment to obtain product.
