Technical FAQs 4

Are electrolyte additives suitable for zinc-nickel flow cell energy efficiencies?

Zinc-nickel flow cell energy efficiencies of 79% achieved. The purpose of this work is to assess the suitability of potential electrolyte additives for zinc morphology control and improved electrochemical performance of the zinc electrode for application in zinc based redox flow battery (RFB) systems.

Can aqueous zinc ion batteries be made universal?

Unlike a radical change of the electrolyte and zinc surface, additive engineering toward the aqueous electrolyte is perhaps the most promising way to counteract the degradation of zinc negative electrode and ensure its universality for different aqueous zinc-ion batteries 25.

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.

What is a zinc based redox flow battery (Zn-RFB)?

The research and development of zinc based redox flow batteries (Zn-RFBs) commenced in the mid-1970s with the zinc-chlorine and zinc-bromine systems.
