▎ 摘　　要

NOVELTY - The object (103) has multiple graphene layers that are formed over an uneven surface. The graphene layer with uniform thickness is formed on a surface of the object. A graphene oxide is negatively charged. The graphene oxide in solution (102) moves to the surface of the object, so that a graphene oxide layer is formed. The graphene layer has adequate pores. Adjacent graphenes are bonded to form a larger net-like or sheet-like network. A graphite is oxidized to form graphite oxide and the graphite oxide is subjected to ultrasonic vibrations to obtain graphene oxide. USE - Object such as uneven object and whisker-like object used in electric device. Uses include but are not limited to electric vehicle, electric power tool, personal computer, mobile phone, display device, lighting device, image reproduction device, electric rice cooker, electric washing machine, air-conditioning system. ADVANTAGE - The object is prevented from being crushed because of sufficient flexibility of the graphene. The graphene layer protects the surface of the object and functions as an active material. The graphene can keep lithium in high density and has high discharge capacity. The thickness of a graphene oxide layer deposited on the object is estimated. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of the apparatus for manufacturing the single-layer or multilayer graphene.
