A computer analysis of the mathematical model for the nickel–cadmium battery discharge with different types of electrodes is presented. The model includes the analysis of processes in the positive nickel-oxide and negative cadmium electrodes; it allows estimating the dependence of the electrode polarization and the battery voltage on the electrolyte concentration, the discharge current density, and the design features of the electrodes. The calculations take into account the mechanisms of processes in the positive and negative electrodes, diffusion, migration and convective transfer of electrolyte components both in the electrodes and in the interelectrode space. The calculated data showed the applicability of the developed model to the studying of the influence of various factors on the discharge characteristics of the nickel–cadmium batteries.
