摘要：

A porous nickel oxide film is successfully synthesized by means of a chemical bath deposition technique from an aqueous nickel nitrate solution The formation of a rock salt NiO structure is confirmed with XRD measurements The electrochemical supercapacitor properties of the nickel oxide film are examined using cyclic voltammetery (CV) galvanostatic and impedance measurements in two different electrolytes namely NaOH and KOH A specific capacitance of similar to 1295 F g(-1) in the NaOH electrolyte and similar to 698 Fg(-1) in the KOH electrolyte is obtained from a cyclic voltammetery study The electrochemical stability of the NiO electrode is observed for 1500 charge-discharge cycles The capacitativi behaviour of the NiO electrode is confirmed from electrochemical impedance measurements (C) 2010 Elsevier B V All rights reserved
