▎ 摘　　要

NOVELTY - The method involves putting obtained lithium molybdate (Li2MoO4) into a muffle furnace under hydrogen-nitrogen mixed gas atmosphere protection for reaction, and obtaining a lithium molybdenum trioxide (Li2MoO3) material. Graphene material with a high specific surface area is added into N-Methyl-2-pyrrolidone (NMP) to form a graphene suspension. Ball-milling is performed on the Li2MoO3 material, the ball-milled material is added into the obtained graphene suspension, and a solution is filtered off and evaporated to obtain a positive electrode sheet of the Li2MoO3 material. USE - Method for preparing a graphene composite positive electrode sheet of a lithium ion capacitor. ADVANTAGE - The method allows a positive electrode sheet of the Li2MoO3 material to be provided with high strength, high conductivity and a high specific surface area and to effectively replace an active carbon positive electrode material and an aluminum current collector, while achieving 1high energy density and high power density. DESCRIPTION OF DRAWING(S) - The drawing shows a graph representing a relationship between energy density and times of cycle.
