▎ 摘　　要

NOVELTY - The article of manufacture i.e. composite electrode (200), comprises an electrically conductive plate; and a set of hybrid layers (240) stacked on the electrically conductive plate, where each of the one or more hybrid layers comprises: a graphene sheet (210); a set of active particles (220) disposed on the sheet; and an ion conducting film (230) disposed on the particles and the sheet. The plate comprises a current collector. The film comprises a polymeric material. The particles comprise a transition metal oxide, an electrically conducting polymer, and a carbon nano structure. USE - The article of manufacture i.e. composite electrode, is useful as an energy storage device including a battery and a supercapacitor (all claimed), where the article of manufacture is a composite electrode, the battery is a lithium-ion battery and the supercapacitor is ultracapacitor, supercondenser, electrochemical doublelayer capacitor and pseudocapacitor. ADVANTAGE - The composite electrode has excellent mechanical robustness and integrity, excellent physical and electrochemical properties and is highly flexible. The composite electrode permits the precise control of the electrode composition and the systematic variation of electrode film parameters. The composite electrode can be formed without the need to thermally or chemically reduce graphite oxide, graphite fluoride, graphene oxide, or graphene fluoride, so that the graphene sheets have low defect densities and very high electrical conductivities, thus achieving a low internal resistance throughout the electrodes and increased rate capability.
