Mathematical modeling and numerical analysis of alkaline zinc-iron flow batteries for energy storage applications

A transient and two-dimensional mathematical model of zinc-iron flow batteries is established to study the influences of electrolyte flow rate and electrode geometry towards the electrochemical performance. The results demonstrate that a high flow rate, high electrode thickness, and porosity are favorable for battery performance. This work provides a comprehensive strategy allowing for the improvement on the practical design of zinc-iron flow batteries.
