▎ 摘　　要

NOVELTY - Preparation of molybdenum sulfide/three-dimensional macroporous graphene involves adding molybdenum acetylacetonate powder as a molybdenum source to a mixed solution of isopropanol, water and glycerol, ultrasonically dispersing, cooling to room temperature after solvothermal reaction, washing with ethanol, performing centrifugal separation of solid phase, drying to obtain molybdenum glyceride ball powder, hydrothermally reacting resulting powder and graphene oxide, cooling to room temperature, washing with deionized water, removing supernatant to obtain solid phase, freeze-drying, adding resultant to a thiourea solution obtained by dissolving 0.08-0.2 mol/L thiourea in a mixed solvent of ethanol and water in volume ratio of 3:1, magnetically stirring, performing solvothermal reaction at 180-200 degrees C for 6-8 hours, naturally cooling to room temperature, washing with ethanol and water, removing supernatant, and calcining under the protection of argon at 800-850 degrees C for 2-2.5 hours. USE - Preparation of molybdenum sulfide/three-dimensional macroporous graphene for negative electrode material (claimed) used for lithium ion battery. ADVANTAGE - The molybdenum sulfide/three-dimensional macroporous graphene having increased specific surface area, electrolyte infiltration ability and lithium ion migration rate can be prepared efficiently. The three-dimensional graphene porous structure provides battery having excellent cycle stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for negative electrode material.
