During charging, Zn 2+ in electrolytes is reduced to metallic Zn on the surface of an anode. Br − in the electrolyte is oxidized to Br 2 molecules on a cathode, where Br 2 molecules and Br − are further complexed into polybromides by a sequestration agent. [30, 43] During discharging, the reverse reactions occur, and metallic Zn is oxidized into Zn 2+, entering …
Among emerging technologies, zinc-bromine flow battery (ZBFB) is widely regarded as one of the most promising candidates due to its nature of high energy density and low cost. Nevertheless, the widespread application of this type of flow battery is still hindered by several critical issues including low power density and zinc dendrite formation.
In terms of the broad suite of diverse technologies involved, potential customers could have many options to choose from in the coming years, and flow batteries have long been part of that conversation.

The speciation of the primary zinc bromide electrolyte with and without a secondary zinc chloride electrolyte is studied in the present work. Raman spectroscopy was carried out on aqueous solutions of zinc bromide at 5 concentrations (2–4 M) to account for the initial and later stages of charging, with 3 concentrations (1–2 M) of zinc chloride.
The zinc-bromine battery is a hybrid redox flow battery, because much of the energy is stored by plating zinc metal as a solid onto the anode plates in the electrochemical stack during charge. Thus, the total energy storage capacity of the system is dependent on both the stack size (electrode area) and the size of the electrolyte storage reservoirs.
