摘要：
A nano graphene-enabled vanadium oxide composite composition for use as a lithium battery cathode active material, wherein the composite composition is formed of one or a plurality of graphene, graphene oxide, or graphene fluoride sheets or platelets and a plurality of nano-particles, nano-rods, nano-wires, nano-sheets, and/or nano-belts of a vanadium oxide with a size smaller than 100 nm (preferably smaller than 20 nm, further preferably smaller than 10 nm, and most preferably smaller than 5 nm), and wherein the graphene, graphene oxide, or graphene fluoride (having a thickness
