NOVELTY - A molybdenum disulfide/graphene (MoS2/rGO) cathode material preparing method involves mixing sodium, thiourea, graphene oxide and deionized water to obtain MoS2/rGO reaction raw material. The MoS2/rGO reaction raw material is placed in hydrothermal reactor, at 180-220 degrees C followed by filtering MoS2/rGO, washing and drying under vacuum oven drying to obtain finished product. USE - Method for preparing molybdenum disulfide/graphene cathode material for lithium ion battery. ADVANTAGE - The method enables preparing cathode material with good process repeatability and strong operability, simple, reliable and cost effective mannner. The battery has high specific capacity and stable cycle performances.
