Vertically aligned carbon nanotubes (VACNTs) has been successfully grown on highly oriented graphite papers with a covalent bonding structure. The covalent bonding feature ensures high frequency response property (cut-off frequency up to 2 kHz, volumetric capacitance at 120 Hz more than 300 mF cm-3) with aqueous electrolytes, 100 nA level equilibrium leakage current and extremely quick stabilization to equilibrium in less than 2 minutes with an ionic liquid electrolyte.
