In this flow battery system 1-1.7 M Zinc Bromide aqueous solutions are used as both catholyte and anolyte. Bromine dissolved in solution serves as a positive electrode whereas solid zinc deposited on a carbon electrode serves as a negative electrode. Hence ZBFB is also referred to as a hybrid flow battery.
