▎ 摘  要

NOVELTY - An electrode coating unit (1) comprises anode (1.1), cathode (1.2), solution (1.3) containing predetermined amount of charged graphene particles (1.4) and an electrode which has mobility due to an electrical field formed by applying potential difference to the cathode (1.2) and anode (1.1). The capacity is increased by coating the positively-charged graphene particles (1.4) on a copper foil due to the negative charge on the cathode electrode (1.2). USE - Electrode coating unit comprising anode with graphene is used in rechargeable energy storage units such as lithium ion batteries (all claimed). ADVANTAGE - The graphene is prevented from forming a graphitic structure during the process and anode capacity is increased to provide a mechanical strength without a polymer binder. The battery swelling is eliminated by the graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of anode (1.1) comprising graphene particles (1.4) which involves preparing a suspension by dissolving the graphene particles (1.4) with predetermined concentration solvent such as isopropyl alcohol or ethanol or methanol or N-methylpyrrolidone and allowing the positively-charged particles to be deposited on the cathode (1.2). The magnesium nitrate is added to the mixture in predetermined ratios and coating the copper foil on the cathode electrode (1.2) in an electrophoretic cell. Coating the charged graphene particles (1.4) on the cathode (1.2) which positioning the anode (1.1) under an electrical field due to applying potential difference using the voltage source to the anode (1.1) and cathode (1.2). DESCRIPTION OF DRAWING(S) - The drawing shows a symbolic view of a storage unit cell and the components. Coating unit (1) Anode (1.1) Cathode (1.2) Solution (1.3) Graphene particles (1.4) Distance (D) Voltage source (V)
