Abstract

An electrode for a lithium-ion battery includes a substrate; and a composite deposited on the substrate, wherein the composite comprises layered graphene comprising mono-, bi- and n-layered graphene, wherein n is an integer selected from 3-about 6; and nanoparticles of a material selected from a cathode active material and an anode active material, wherein the surface of each of said nanoparticles is coupled to and conformally coated with said layered graphene, and wherein said layered graphene is not graphene oxide and is not reduced graphene oxide.
