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.

What are alkaline zinc-based flow batteries?

Alkaline zinc-based flow batteries (AZFBs) are considered promising candidates owing to Zn abundance, low cost, and environmental friendliness [, , ]. Typical AZFBs using Zn (OH) 42− anolyte and Fe (CN) 63− /Fe (CN) 64− catholyte have a high cell voltage (>1.7 V) , leading to a high power density.

Are alkaline Zn-Fe flow batteries suitable for large-scale energy storage?

The alkaline Zn-Fe flow battery stably operated for over 500 h, achieving an EE of 86.3 % at 80 mA cm−2. Alkaline zinc-based flow batteries (AZFBs) are considered one of the most promising candidates for large-scale energy storage owing to Zn abundance, cost effectiveness, intrinsic safety and eco-friendliness.
