The liquid metal battery is a promising candidate for grid-scale energy storage. The reaction kinetics are strongly influenced by transport near the electrode/electrolyte interface. Here we present a magnetohydrodynamics-based model in Lithium-Bismuth liquid metal batteries. The model uses a combination of stream functions to represent the flow in the positive electrode. By solving the reaction-advection-diffusion equation in Bi electrodes, we are able to accurately predict the operating voltage, kinetic losses, state of charge, and concentration profiles in real time. The outcome of this work represents the first attempt to couple electrochemistry and magnetohydrodynamics in liquid metal batteries and can be used to guide future development of battery management systems.
