In this work, a mathematical model based on porous electrode theory was developed in COMSOL Multiphysics^® simulation software to simulate discharge behavior of primary Zn/MnO2 alkaline batteries. The model integrates microscopic and macroscopic phenomena through incorporation of species diffusion in pseudo-2D geometries for both the anode and cathode. The predicted battery performance shows good agreement with experiments under various constant-current and current-interrupt discharge conditions. These results provide battery design engineers better understanding of polarization sources and insights that would otherwise be laborious to obtain.
