NOVELTY - Preparation of graphene-supported highly conductive molybdenum sulfide nanomaterial involves dispersing graphene oxide in N,N-dimethylformamide, adding ammonium tetrathiomolybdate and urea, mixing well, adding hydrazine hydrate, dispersing uniformly, and reacting at 150-200 degrees C. USE - Preparation of graphene-supported highly conductive molybdenum sulfide nanomaterial used for preparing graphene-supported highly conductive molybdenum sulfide nanomaterial-polypropylene modified diaphragm material and graphene-supported highly conductive molybdenum sulfide nano/sulfur composite material for forming electrode for lithium-sulfur battery (all claimed). ADVANTAGE - The method produces graphene-supported highly conductive molybdenum sulfide nanomaterial which ensures high-efficiency synergistic effect of the positive electrode and the separator of the lithium-sulfur battery, enhances the adsorption/catalysis ability of polysulfides, and ensures cycle performance and high energy density of the battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of graphene-supported highly conductive molybdenum sulfide nanomaterial-polypropylene modified diaphragm material; (2) preparation of graphene-supported highly conductive molybdenum sulfide nano/sulfur composite material; (3) preparation of electrode; and (4) lithium-sulfur battery.
