▎ 摘　　要

NOVELTY - The method involves growing porous vertical graphene electrode structures on respective spaced apart collectors by PECVD (405) and filling the pores on each structure with metal oxide (410) to provide redox capacitance, creating a supercapacitor without using catalyst for growth and a binder for mixing the electrode structures and or metal oxide. The graphene structures are separated from each other by a separator and serve as carbon nanowalls. A hydrocarbon source may be used for growth. USE - Method for producing hybrid supercapacitor, particularly metal oxide vertical graphene hybrid supercapacitor. ADVANTAGE - Vertical graphene has sufficient conductivity to reduce electrode material resistance, especially without any catalysts or binders. Adding a metal oxide may enable redox capacitance, increasing the total capacitance, which may increase energy density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an apparatus for producing hybrid supercapacitor. DESCRIPTION OF DRAWING(S) - The drawing shows the flow diagram of a process for growing vertical graphene electrodes.
