Applying electric field in the ammonium based solution has been used for the fabrication of different forms of copper hydroxide nanostructures. The supercapacitance performance of synthesized nanostructures has been investigated and high specific capacitance of 178 F/g at scan rate of 20 mVs-1 was obtained. The fast, simple and low cost electric field enhanced synthesis method proposed here can be used for fabrication of high performance Cu(OH)2 nanostructured supercapacitance electrodes.
