A mathematical model of a sealed nickel-cadmium battery
- Dept. of Chemical Engineering, Texas A and M Univ., College Station, TX (US)
This paper presents a mathematical model for the charge and discharge of a sealed nickel-cadmium (Ni- Cd) battery. The model is used to study the effect of transport properties of the electrolyte and kinetic parameters of the electrode reactions on the cell performance during the charge and discharge period. The model can also be used to demonstrate the changes of cell performance during cycling. Some comparisons between model predictions and experimental results indicate that the model predictions appear to fit the experimental data well. Sensitivity analyses illustrate that the sealed nickel-cadmium battery operates under activation control. It is also shown theoretically that oxygen generated on the positive electrode during charge is reduced electrochemically on the negative electrode.
