Oxygen Recombination in Sealed Ni‐Cd Cells with Fiber Substrates

Abstract

Oxygen recombination in a positive-limited-sealed Ni-Cd cell was investigated. The electrodes were made by electrochemical impregnation of nickel fiber substrates. The negative electrode capacity was 1.7 times that of the positive electrode capacity, thus preventing hydrogen evolution during overcharge. A mode] was developed to compute the recombination parameters during charge and overcharge of the positive-electrode-limited sealed Ni-Cd cell. The model was used to study the effect of electrolyte saturation level, initial state of charge of the positive electrodes, and charge rate on recombination kinetics in sealed Ni-Cd cells. A comparison of the recombination rate at rest was made with that during overcharge.) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.

Studies on Oxygen Recombination at the Rechargeable Iron Electrode in an Alkaline Battery

“…[13][14][15] V. V. Viswanathan et al also studied the effect of electrolyte saturation level, charge rate, and recombination kinetics under both steady-state and non-steady state conditions for the cadmium electrode. 16 Among these parameters the quantity of the electrolyte in the cell was identified to be the most crucial in determining the rate of recombination. The flooded condition with electrolyte saturation resulted in a low recombination rate.…”
