A battery consists of two electrodes – the anode and cathode, typically made of different materials – as well as a separator and electrolyte, a chemical medium that allows for the flow of electrical charge. During battery discharge, electrons flow from the anode into an external circuit and then collect at the cathode.

Most of the models existing in the literature for flow batteries include the basic models of transports of mass, electrochemical kinetics, heat and charge, as well as the momentum (Xu and Zhao 2015).
