Computer simulation of the discharge of metal electrodes in batteries with solid electrolytes

The computer simulation of the dissolution during discharge of silver electrodes in batteries and other devices with various silver-conducting solid electrolytes was carried out. The model of the pseudo-porous electrode represents small silver spheres, distributed in a solid electrolyte matrix. Various parameters simulated were: diameter of silver particles, silver to electrolyte relationship within the electrode, thickness of the electrode, conductivity of the electrolyte, discharge current and thickness of the separator. Calculated distribution of current in the electrode and the discharge curves at various parameters were obtained. A comparison of the calculated and experimental discharge curves was carried out. The good correspondence of these curves testifies to adequacy of the surveyed model of the dissolution of metal electrode for devices with solid electrolytes. Optimal parameters of the electrode are recommended depending on the use of these devices with solid electrolytes.
