▎ 摘　　要

NOVELTY - Battery formed by the process of: 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 direct electrical communication with at least one graphene layer as part of the anode, is claimed. USE - Used as a battery. ADVANTAGE - The battery is produced using low cost commodity chemicals as starting materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a battery formed by the process of: dispersing graphene with a surfactant to form a first mixture; providing metal oxide in an aqueous solution to form a second mixture; mixing the first and second mixtures 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 direct electrical communication with at least one graphene layer as part of the anode.
