▎ 摘　　要

NOVELTY - Preparing nanocomposite anode material, comprises stirring and adding modified graphene aqueous solution into N,N-dimethylformamide to obtain a suspension, stirring, heating suspension, dropping nickel(II) acetate tetrahydrate aqueous solution, stirring, refluxing, cooling to room temperature, washing with deionized water and centrifuging to obtain a precipitate, adding deionized water into the precipitate, drying at a constant temperature, cooling, washing, centrifuging and drying to obtain the precursor, placing the precursor in a muffle furnace and heating, and cooling to room temperature, grinding and mixing solid product with sodium dihydrogen hypophosphite powder, placing in a tube furnace, filling with nitrogen for protection, heating, and cooling to room temperature, adding carbon disulfide solution into the sulfur powder, stirring, adding N-methylpyrrolidone, adding the composite material, heating, stirring until the solvent is completely volatilized, and drying. USE - The method is useful for preparing nanocomposite anode material. ADVANTAGE - The method provides graphene with good conductivity and high specific surface, which is good for improving the conductivity, dispersion degree of the sulfur, and high catalytic performance. The nickel phosphide is combined with the graphene as the carrier of sulfur, which improves the circulation stability of the sulfur electrode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for nanocomposite anode material.
