Correspondence: thwang@ncepu .cn. Abstract: Zinc–bromine redox flow battery (ZBFB) is one of the most promising candidates for large-scale energy storage due to its high energy density, low cost, and long cycle life. However, numerical simulation studies on ZBFB are limited.
The main disadvantage for hybrid zinc RFBs is that the energy storage is limited by the amount of zinc that can be plated on the electrode. The theoretical plating density for zinc is only 5.86 Ah cm −3, considerably less than that of iron (7.54 Ah cm −3 ) and other metals.

Energy storage is the main differing aspect separating flow batteries and conventional batteries. Flow batteries store energy in a liquid form (electrolyte) compared to being stored in an electrode in conventional batteries. Due to the energy being stored as electrolyte liquid it is easy to increase capacity through adding more fluid to the tank.
Alkaline zinc-based flow batteries such as alkaline zinc-iron (or nickel) flow batteries are well suited for energy storage because of their high safety, high efficiency, and low cost.
