▎ 摘　　要

NOVELTY - The capacitor (10) has a graphene sheet (20) e.g. atomic monolayer sheet, placed in a thin film electrode layer (30). A thin/ultrathin nano-structured vanadium oxide monolayer (15) is placed on the graphene sheet defines vanadium oxide/ graphene composite. A pair of oppositely placed electrodes is connected in electric communication to a capacitor body. A set of carbon spacers is placed between the graphene sheet and the vanadium oxide monolayer. The thin film electrode layer is typically fabricated upon the graphene sheet to allow the composite to perform electric communication or conduction. USE - Capacitor e.g. electrochemical super-capacitor, electrical double layer capacitor, for military and commercial device for a high power density application e.g. laser system application or electric vehicle (EV)/hybrid electric vehicle (HEV) system application. ADVANTAGE - The capacitor is made of vanadium oxide for an electrically conducting support, so that a single carbon layer of the graphene sheet provides minimized space constraints to the capacitor. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) an electronic device (2) an energy storage device. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a capacitor.
