We demonstrate, for the first time, high‐efficiency supercapacitors by utilizing chemical vapor deposition (CVD)‐grown graphenes hybridized with multiwalled carbon nanotubes (CNTs). A single‐layer graphene was grown by simple CVD growth method, and transferred to polyethylene terephthalate substrates. The bare graphenes were further hybridized with multiwalled CNTs by drop‐coating CNTs on graphenes. The supercapacitors using bare graphenes and graphenes with CNTs revealed that graphenes with CNTs resulted in enhanced supercapacitor performances of 2.2‐ (the mass‐specific capacitance) and 4.4‐fold (the area‐specific capacitance) of those of bare graphenes. Our strategy to improve electrochemical performance of CVD‐grown graphenes is advantageous for large‐scale graphene electrodes due to high electrical conductivity of CVD‐grown graphenes and cost‐effectiveness of using multiwalled CNTs as compared to conventional employment of single‐walled CNTs.
