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 .
However, there are some significant scientific concerns surrounding the Zn metal electrode to obstruct the large-scale application of zinc-ion batteries, such as poor Coulombic efficiency (CE), byproduct formation, and Zn dendrites formation [ 2, 6, 7 ].
Notably, during the Zn plating process, the surface of the Zn anode is negatively charged, and it can attract the positive charge carrier Zn ( in neutral/mildly acidic electrolytes, while repelling the negative charge carrier Zn in alkaline electrolytes.
Normally, the plating of zinc species on the anode experiences three processes: mass transfer, desolvation, and receiving electrons to be reduced to zinc metal .
Conversely, the high tunability of zinc powder (Zn-P) makes it an ideal choice for zinc-based batteries, seamlessly integrating with current battery production technologies. However, challenges such as contact loss, dendrite formation, and a high tendency for corrosion significantly hamper the performance enhancement of Zn-P anodes.
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.
