Charge Efficiency and Charge Utilization in the Sealed Nickel-Cadmium Cell.
Abstract
The charge efficiency of the nickel-cadmium cell is found to be 100% up to the state of charge where oxygen evolution begins to take place. Inefficiencies at lower states of charge are due to poor utilization of capacity on discharge rather than to any inefficiency in rechargability. The dependence of the utilization efficiency on charge and discharge rates is reported. The results are consistent with the hypothesis that the utilization of capacity in the nickel electrode is limited by the formation of a depletion layer at the current collector-active material interface.
