Abstract
The present invention provides an anode electrode of a lithium-ion battery, comprising an anode active material-coated graphene sheet, wherein the graphene sheet has two opposed parallel surfaces and at least 50% area of one of the surfaces is coated with an anode active material and wherein the graphene material is in an amount of from 0.1% to 99.5% by weight and the anode active material is in an amount of at least 0.5% by weight (preferably at least 60%), all based on the total weight of the graphene material and the anode active material combined.
