▎ 摘　　要

NOVELTY - Anode active material, comprises graphite, inorganic coating layer attached to the graphite, and metal oxide layer attached to the outside of the inorganic coating layer. The inorganic coating layer contains graphene or carbon nanotubes, metal oxide layer is at least one oxide among aluminium, magnesium, zirconium, titanium, silver, nickel and molybdenum. USE - The anode active material is useful in lithium-ion battery (claimed). ADVANTAGE - The anode active material utilizes fast-charging graphite which has moderate processing performance, and the slurry mixing method used makes the slurry stable, the pole piece is not easy to drop powder, and the anode sheet density is 220 g/m2; and has excellent fast-charging performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Preparing anode active material; Lithium-ion battery anode; and Preparing lithium-ion battery anode. The method utilizes dispersant, solvent, conductive paste, conductive powder and anti-cracking agent.
