Mechanism and kinetics of iron electrode dissolution in KOH electrolytes

Conference ·
OSTI ID:6246162
The studies described in this paper were made to determine the effects of adding LiOH, K/sub 2/S, or FeO to the KOH electrolytes, and the variation of KOH concentration on the dissolution behavior of iron electrodes. LiOH is used as a standard component in alkaline electrolytes in nickel-iron cells, and it has been reported that the charge inefficiency of the iron electrode caused by H/sub 2/ gas evolution can be reduced by the addition of sulfur-bearing anion to the electrolyte. The study of the FeO additive was included solely to aid in the understanding of the iron dissolution mechanism. Studies were performed using both cyclic volammetric and rotating ring-disc electrode (RRDE) techniques.
