▎ 摘　　要

NOVELTY - Forming a nanocomposite material comprises either (a) providing metal oxide and graphene in a solvent to form a suspension, (b) applying the suspension to a current collector, and (c) evaporating the solvent to form a nanocomposite material comprising at least one metal oxide in electrical communication with at least one graphene layer; or (a)-(b) as above per se, evaporating the solvent to form an anode, connecting the anode to a cathode having lithium ions and an electrolyte to form a battery, and electrochemically cycling the anode to form a nanocomposite material. USE - The method is useful for forming a nanocomposite material, which is used in a battery (all claimed), preferably in lithium ion battery. ADVANTAGE - The method: provides the nanocomposite material, which exhibits unique electrochemical property; and utilizes low cost chemicals as starting material, thus cost-effective. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a nanocomposite material formed by the method; and (2) a battery formed by the process, comprising providing metal oxide and graphene in a solvent to form a suspension, applying the suspension to a current collector, evaporating the solvent to form an anode, providing a cathode and an electrolyte in electrical communication with the anode, and electrochemically cycling the anode to form a nanocomposite material comprising at least one metal oxide in electrical communication with at least one graphene layer.
