▎ 摘  要

NOVELTY - The preparation method of molybdenum disulfide oxide/carbon anode material involves mixing pretreated wet tissue with graphene oxide, drying, coating a layer of graphene oxide on wet tissue, carrying out hydrothermal reaction on wet tissue loaded graphene oxide with sodium molybdate and thiourea at 90-240 degrees C for 1-24 hours, then calcining at 500-1200 degrees C for 1-10 hours under nitrogen atmosphere to get molybdenum disulfide/carbon anode material, and then calcining in the presence of oxygen at 100-600 degrees C for 1-5 hours to get product. USE - The method is useful for preparing molybdenum disulfide oxide/carbon anode material, which is useful in lithium ion battery. ADVANTAGE - The method prepares molybdenum disulfide oxide/carbon anode material with high electronic conductivity, large specific surface area, excellent physical and chemical stability and improved reversible specific capacity. DETAILED DESCRIPTION - The preparation method of molybdenum disulfide oxide/carbon anode material involves mixing pretreated wet tissue with graphene oxide, drying, coating a layer of graphene oxide on wet tissue, carrying out hydrothermal reaction on wet tissue loaded graphene oxide with sodium molybdate and thiourea at 90-240 degrees C for 1-24 hours, then calcining at 500-1200 degrees C for 1-10 hours under nitrogen atmosphere to get molybdenum disulfide/carbon anode material, and then calcining in the presence of oxygen at 100-600 degrees C for 1-5 hours to get product. The molybdenum disulfide oxide is of formula: MoS(2-x)Ox (I). x=0.1-0.4.
