▎ 摘　　要

NOVELTY - Preparation of lithium ion supercapacitor anode plate comprises mixing lithium carbonate and molybdenum trioxide, feeding to muffle furnace, reacting under hydrogen and nitrogen mixed protective atmosphere, adding high specific surface area graphene material to N-methyl-2-pyrrolidone, ball milling lithium-molybdenum material, adding to graphene suspension, and evaporating solvent. USE - Method for preparing lithium ion supercapacitor anode plate. ADVANTAGE - The material has high energy density, conductivity and specific surface area. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of lithium ion supercapacitor comprising mixing graphite microbeads or cathode material, conductive agent, adhesive and N-methyl-2-pyrrolidone, coating on cathode current collector copper foil, drying, connecting lithium ion supercapacitor anode plate, stacking, injecting electrolyte in battery shell, and sealing. DESCRIPTION OF DRAWING(S) - The drawing shows a graph representing a relationship between energy density and times of cycle.
