| Abstract: | The electrochemical reactions on nickel electrode in alkaline media were studied with transient constant current technique. The effect of charge and discharge current on the electrode characteristics was discussed. Cobalt ion implantation was applied to research the charge/discharge character of nickel electrode. The reactions of oxygen and hydrogen evolution on the electrode surface were affected by implanted cobalt directly. The amount of NiOOH transformed from Ni(OH)2 was increased after cobalt ion implantation and the charge efficiency of the electrode was improved. |
