▎ 摘　　要

NOVELTY - Carbon-coated graphite anode material comprises 70-80 wt.% graphite, 5-10 wt.% graphene layer coated on the outer periphery of the graphite and 12-25 wt.% carbonaceous layer coated on the graphene layer, where the graphene layer comprises graphene oxide dispersion liquid, the carbonaceous layer comprises cracked carbon using carbon precursor and the carbon precursor comprises organic matter. USE - As carbon-coated graphite anode material. ADVANTAGE - The anode material has long cycle life, high specific capacity and long service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing carbon-coated graphite anode material involving (i) dispersing graphite in a solvent, uniformly mixing, adding graphene oxide dispersion liquid, ultrasonically treating for 20-60 minutes, dripping polyacrylamide to coagulate the graphene oxide dispersion liquid, and taking precipitation material, (ii) heating and reducing the precipitation material to graphene at a high temperature and cooling to obtain graphite material covering the graphene layer, dispersing the graphite material covering the graphene layer in a carbon precursor, uniformly mixing and (iii) performing carbon coating treatment to form crude carbon-coated graphite anode material product and carbonizing the crude carbon-coated graphite negative electrode material.
