Technical FAQs 4

Are neutral zinc–iron flow batteries a good choice?

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 suffer from Zn 2 Fe (CN) 6 precipitation due to the Zn 2+ crossover from the anolyte.

Are zinc-iron redox flow batteries safe?

Authors to whom correspondence should be addressed. Zinc–iron redox flow batteries (ZIRFBs) possess intrinsic safety and stability and have been the research focus of electrochemical energy storage technology due to their low electrolyte cost.

How much does a zinc/iron battery cost?

The battery exhibited very high power density, energy density, and efficiencies. Most importantly, by using the self-made, low-cost PBI membrane with ultra-high chemical stability, 3D porous carbon felt electrode, and inexpensive zinc and iron active materials, the cost of zinc/iron battery system is even lower than $90/kWh.

Are zinc-iron flow batteries suitable for grid-scale energy storage?

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.
