Graphical abstractA facile and efficient technique for the preparation of high-density and vertically oriented graphene nanosheets (VOGNs) directly on graphite plates is described. The VOGNs are obtained by electrochemical anodization of graphite producing aligned graphene oxide (G@GO) that adheres strongly to the graphite substrate (G@rGO) and reduction. The integrated supercapacitors composed of the G@rGO electrodes boast excellent rate performance and long-term cycling stability such as high volumetric capacitance of 3.9Fcm-3 in 6M KOH.
