| Popis: | Nitrogen containing carbon materials with metal of oxides (Fe, Ni, Co) prepared by thechemical precipitation method have been shown to be outstanding novel materials forelectrochemical capacitors. The electrochemical properties of the electrodes have been studied byconsidering the effect of the mole ratio of metals. Cyclic voltammetric measurements indicate thatnickel, cobalt and iron oxides increase specific capacity of electrochemical capacitors up to 260 F/gin 30% KOH electrolyte. Impedance studies show that the enhanced electrical properties and highfrequency response are attributed to the presence of Fe oxides. |
