1D Isothermal Zinc-Silver Oxide Battery

Application ID: 17229

Zinc-Silver oxide (Zn-AgO) batteries are used in different industries due to their high capacity per unit weight. In this work, discharge of a Zn-AgO battery is simulated using the Battery with Binary Electrolyte interface. The electrochemical reactions in the positive and negative electrodes lead to changes in porosity and species concentration in the electrodes. This is modeled using Domain ODEs and DAEs interfaces.

This tutorial example can be used for studying the performance of Zn-AgO batteries and for providing insights towards cell design. In this work, model analysis is done to relate the drop in cell voltage at the end of discharge to the spcecies concentration in the electrodes, thereby indicating the limiting electrode in the cell.

This model example illustrates applications of this type that would nominally be built using the following products:
