3D carbon nanostructures combined with metal oxides are promising architectures to improve both specific capacity and power density of electrochemical energy storage systems. Their open structure and porosity provide a large space for active sites and high ion diffusion rates. Vertically oriented graphene nanowalls (VG) covered by Si have been proposed for increased supercapacitor performance<\/a>. The incorporation of Si in VG\/FGS provides an areal capacitance up to 16.4 mF cm\u22122, which is a factor 2 and 1.4 greater than that of bare substrate and VG\/FGS, respectively.
