The present work demonstrates the preparation of NiO nanoflakes via potentiodynamic electrodeposition method. The structural and morphological analyses of the film have been presented. The pseudocapacitive properties are tested using cyclic voltammetry, charge-discharge and electrochemical impedance spectroscopy. The maximum value of specific capacitance obtained is 222 Fg(-1).
