▎ 摘　　要

NOVELTY - Method for preparing graphene-coated anode material involves: (i) dispersing graphene or graphene oxide in solvent, and dispersing for 2-40 hours by mechanical action to obtain graphene or graphene oxide slurry with a solid content of 0.5-20%; (ii) adding anode material suspension into graphene or graphene oxide slurry under ultrasonic state, and drying precursor; and (iii) sintering precursor in inert gas atmosphere at high temperature. USE - Preparation method of graphene-coated anode material of lithium ion battery (claimed). ADVANTAGE - The graphene is uniformly, continuously and densely covers a surface of the anode material particles, thus improving electronic conductivity and lithium ion migration rate of the anode material of the lithium ion battery, so as to obviously improve power performance and cycle stability of the lithium ion battery. The method has simple and mature technique, low cost, and is suitable for large-scale continuous production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-coated anode material, prepared by above method.
