Modelling A Nickel Cadmium Battery As A Homogeneous Device

A computer model of the NickeL-Cadmium (Ni-Cd) battery cell has been developed by Texas A&M University for the Jet Propulsion Laboratory and NASA. This one-dimensional macro-homogeneous model predicts performance for Ni-Cd battery cells based on electrochemical phenomena. Reaction rates, concentrations, current densities, porosities, and potentials are predicted over a range of conditions. This paper provides a description of the model, some initial results, and plans for continued development.
