▎ 摘　　要

NOVELTY - Fabrication (100) of graphene involves providing (110) a patterned substrate, depositing (120) graphene oxide on the patterned substrate, and reducing (130) the graphene oxide to graphene. USE - Fabrication of graphene used for electrode of sandwich-style capacitor (all claimed). Can also be used for pseudocapacitor, electrical double-layer capacitor, rechargeable battery, ultrabattery, flow battery, and fuel cell. ADVANTAGE - The method produces graphene with improved spacing between graphene layers and improved level of conversion of graphene oxide to graphene, thus improving both energy density and power density of the electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of fabrication of the graphene.
