| Abstract: | Thin films of nickel oxide as ultracapacitor electrode materials are prepared by heating nickel hydroxide fabricated by cathode electrodeposition method from the solution containing nickel nitrate. The X-ray diffraction (XRD), fourier transform infrared (FTIR) and thermogravimetry (TG) are used to analyze the electrodeposited film materials nickel oxide and nickel hydroxide. Using the cyclic voltammogram technique, these nickel oxide films electrodeposited can provide a specific capacitance of 55 F/g, and the specific energy and specific power of these films are 34 J/g and 15 W/g, respectively. In addition, these functional films formed by electrochemical deposition as ultracapacitor electrode materials have good mechanical strength and long cycle life. |
