▎ 摘　　要

NOVELTY - An anode electrode comprises an anode active material-coated graphene sheet in which graphene sheet has two opposed parallel surfaces and at least 50 area% of one of surfaces is coated with anode active material, and 0.1-99.5 wt.% graphene material. The content of anode active material is 0.5 wt.% or more with respect to total content of graphene material and anode active material. USE - Anode electrode is used for lithium-ion battery (claimed) of power tool and electric vehicle. ADVANTAGE - The anode electrode has low irreversible capacity and high cycle life, tap density, reversible capacity, and compatibility with electrolyte. The secondary particles in the anode electrode can be easily handled. The graphene sheet has high electrical conductivity and thermal conductivity, and exhibits highest intrinsic strength and highest intrinsic thermal conductivity, thereby providing excellent structural integrity to the electrode. The lithium-ion battery provided with the anode electrode has high capacity and long charge-discharge cycle life. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) lithium-ion battery; and (2) preparation of anode electrode.
