Pasted nickel electrodes for alkaline batteries were prepared by deposition of the electrodic mixture slurry (active material, conductive additives and binder) on nickel foam substrate and on nickelated iron grid, respectively.The electrochemical behaviour of these electrodes in 6N KOH electrolyte has been investigated by cyclic voltammetry and performance curves. From cyclic voltammograms were determined the electrochemical processes that occur on the electrodes in normal conditions, at overcharge and overdischarge.The coulombic efficiencies, calculated from charge-discharge curves in galvanostatic regime, demonstrated the better performance of pasted electrodes on nickel foam substrate.
