Slow Potentiodynamic Studies of Porous Alkaline Iron Electrodes

Abstract
A slow potentiodynamic method where a porous iron electrode is fully discharged and charged has been used to study the reactions of the alkaline iron electrode. Electrode thickness, temperature, average porosity, number of armor nets, electrolyte concentration, and carbonate contents have been varied. The experiments show that high temperature, porosity, and concentration increases the charge efficiency of the electrodes. High concentration promotes the direct oxidation of Fe to , and concentrations up to 250 g/liters do not influence the reactions of the electrode considerably.
