▎ 摘 要
NOVELTY - The method involves forming a graphene layer (22) on a substrate (26), and forming a spacer layer which is graphene oxide layer (24a) on the graphene layer. An upper graphene layer is formed on the spacer layer. The spacer layer is formed by maintaining a desired distance between the graphene layer and the upper graphene layer. The spacer layer is comprised of several graphene sheet fragments. The graphene sheet fragments are formed by adjusting a graphene growth time to be shorter than a graphene growth time of the graphene layer. USE - Method of manufacturing multi-layered graphene film used as electrode in manufacture of energy storage device such as battery and supercapacitor. ADVANTAGE - Since the contact area between the electrolyte and the first graphene layer is increased when the multi-layered graphene film is used as an electrode of an energy storage device, the capacity of the energy storage device is increased. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method of manufacturing the energy storage device. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view illustrating the process of manufacturing multi-layered graphene film.
