▎ 摘　　要

NOVELTY - Preparation of graphene-based anode material involves dispersing titanium carbide (MXene)/graphene composite material, copper salt and sulfur source in a solvent, obtaining a mixed solution, placing the mixed solution in a closed pressure system, solvothermally reacting at 100-180 degrees C for 18-24 hours, obtaining copper sulfide/MXene/graphene nanocomposite material, mixing the nanocomposite material with elemental sulfur, grinding, and reacting at 155-180 degrees C for 10-18 hours. USE - Preparation of graphene-based anode material used for lithium-sulfur battery (all claimed). ADVANTAGE - The method provides graphene-based anode material, which improves the electrochemical performance of lithium-sulfur battery.
