▎ 摘 要
NOVELTY - A lithium ion battery anode material coating method involves ultrasonically dispersing graphite in solvent to obtain a graphite suspension liquid and ultrasonically dissolving graphite oxide in solvent to obtain graphene oxide solution. The graphene oxide solution is added into graphite suspension liquid at mass ratio of 0.01-0.3:1, ultrasonically mixed, and the solvent is removed to obtain dried solid powder, followed by processing solid powder at 600-1000 degrees C for 1-4 hours under inert atmosphere and cooling to obtain graphite anode material of lithium ion battery coated with the graphite. USE - Method for coating lithium ion battery anode material. ADVANTAGE - The method enables coating anode material with excellent coating effect, high purity, good cycle performance in simple, low energy dissipation, environmentally friendly, and cost effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium ion battery anode material obtained by the method.
