Claim:
1. A lithium-ion battery anode comprising: multiple nano graphene-enhanced particulates, wherein at least one of said particulate is formed of a single or a plurality of graphene sheets and a plurality of fine anode active material particles with a size smaller than 10 μm, and the graphene sheets and the particles are mutually bonded or agglomerated into said particulate with at least a graphene sheet embracing inside an envelope constituted by the graphene sheet or multiple graphene sheets said anode active material particles and said a single or plurality of graphene sheets, and wherein said graphene sheets are in an amount of at least 0.01% but less than 99% by weight and said anode active material is in an amount of at least 0.1% by weight, all based on the total weight of said particulate.
