In this research, the electrochemical characteristics of electrodes consisting of activated carbon (AC) and NiO/AC composites were investigated. All experimental were done in a three- electrode system by means of cyclic voltammetry and galvanostatic charge/discharge in 1M KOH and specific capacity was calculated in the positive and negative potentials. The cyclic voltammetric of electrodes demonstrated that presence of NiO in NiO/AC composites increase the maximum applicablepotential from 0.2V/SSCE in carbon active to 0.5V/SSCE in composites. Also, it was not possible to use composites with high amount of carbon at low current density. The specific capacity of compositeswith 0.426 weightratio of AC/Ni is the best one in comparison to other compositions.
