Integrated carbon spheres in the manner of agglomerate of joined ones were grown on nickel foam substrates by a hydrothermal technique, which could be directly used as an electrode for supercapacitors. This avoided the exploitation of adhesive and thereby significantly decreased the resistance of the electrode. The electrode exhibited a rectangular cyclic voltammogram even at a high scan rate of 10 mV/s and its specific capacitance was as high as 196.43 F/g at the current density of 1 A/g.
