Abstract

Nitrogen containing carbon materials with metal of oxides (Fe, Ni, Co) prepared by the
chemical precipitation method have been shown to be outstanding novel materials for
electrochemical capacitors. The electrochemical properties of the electrodes have been studied by
considering the effect of the mole ratio of metals. Cyclic voltammetric measurements indicate that
nickel, cobalt and iron oxides increase specific capacity of electrochemical capacitors up to 260 F/g
in 30% KOH electrolyte. Impedance studies show that the enhanced electrical properties and high
frequency response are attributed to the presence of Fe oxides.
