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 .
A high performance and long cycle life neutral zinc-iron redox flow battery. The neutral Zn/Fe RFB shows excellent efficiencies and superior cycling stability over 2000 cycles. In the neutral electrolyte, bromide ions stabilize zinc ions via complexation interactions and improve the redox reversibility of Zn/Zn 2+.
Among which, zinc-iron (Zn/Fe) flow batteries show great promise for grid-scale energy storage. However, they still face challenges associated with the corrosive and environmental pollution of acid and alkaline electrolytes, hydrolysis reactions of iron species, poor reversibility and stability of Zn/Zn 2+ redox couple.
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.
Significant technological progress has been made in zinc-iron flow batteries in recent years. Numerous energy storage power stations have been built worldwide using zinc-iron flow battery technology. This review first introduces the developing history.
Notably, the zinc-bromine flow battery has become one of the most mature technologies among numerous zinc-based flow batteries currently in existence, which holds the most promise for the future. Compared with other redox couples, ZnBr 2 is highly soluble in the electrolyte, which enables zinc-bromine flow battery a high energy density.
