Compared with the energy density of vanadium flow batteries (25∼35 Wh L-1) and iron-chromium flow batteries (10∼20 Wh L-1), the energy density of zinc-based flow batteries such as zinc-bromine flow batteries (40∼90 Wh L-1) and zinc-iodine flow batteries (∼167 Wh L-1) is much higher on account of the high solubility of halide-based ions and their high cell voltage.
Notably, these interfacial engineering processes are general to most AZFB systems and can achieve high power density (115 mW/cm 2 for Zn-iodine flow batteries, 255 mW/cm 2 for Zn-bromine flow batteries, and 260 mW/cm 2 for Zn-vanadium flow batteries), areal capacity, and long cycling performance for all validation models (16, 25, 28, 37–41).

Impressively, even at an ultrahigh power density of 13 kW kg −1 (exceeding the maximum power density of electrochemical capacitors), it still retains a high energy density of 99 Wh kg −1.
Because of all the above reasons, practical batteries are expected to have ZnBr 2 concentrations of at least 2-3M and, even at these concentrations, it is unlikely for the energy density values to exceed 45-50 Wh/L.

Zinc-bromine flow batteries (ZBFBs) offer great potential for large-scale energy storage owing to the inherent high energy density and low cost.
