Neutral zinc–iron flow batteries (ZIFBs) remain attractive due to features of low cost, abundant reserves, and mild operating medium. However, the ZIFBs based on Fe (CN)63–/Fe (CN)64– catholyte suffe...
Among the above-mentioned flow batteries, the zinc-based flow batteries that leverage the plating-stripping process of the zinc redox couples in the anode are very promising for distributed energy storage because of their attractive features of high safety, high energy density, and low cost .
The history of zinc-based flow batteries is longer than that of the vanadium flow battery but has only a handful of demonstration systems. The currently available demo and application for zinc-based flow batteries are zinc-bromine flow batteries, alkaline zinc-iron flow batteries, and alkaline zinc-nickel flow batteries.
Among the above-mentioned zinc-based flow batteries, the zinc-bromine flow batteries are one of the few batteries in which the anolyte and catholyte are completely consistent. This avoids the cross-contamination of the electrolyte and makes the regeneration of electrolytes simple.
Abstract The decoupling nature of energy and power of redox flow batteries makes them an efficient energy storage solution for sustainable off-grid applications. Recently, aqueous zinc–iron redox flow
