Indeed, not all zinc-based flow batteries have high energy density because of the limited solubility of redox couples in catholyte. In addition to the energy density, the low cost of zinc-based flow batteries and electrolyte cost in particular provides them a very competitive capital 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.
Secondly, the deposition of zinc on the negative electrode side still suffers from various common problems of zinc-based flow batteries, which are manifested in technical difficulties such as serious zinc dendrite problems, easy hydrolysis to form precipitation under neutral conditions, and poor cycle stability.
Benefiting from the uniform zinc plating and materials optimization, the areal capacity of zinc-based flow batteries has been remarkably improved, e.g., 435 mAh cm-2 for a single alkaline zinc-iron flow battery, 240 mAh cm -2 for an alkaline zinc-iron flow battery cell stack, 240 mAh cm -2 for a single zinc-iodine flow battery .
