Oxygen recombination in a positive-limited-sealed Ni-Cd cell was investigated. The electrodes were made by electro-chemical 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 model 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.
