Technical FAQs 4

Are alkaline flow batteries suitable for stationary energy storage?

Alkaline flow batteries are attracting increasing attention for stationary energy storage. Very promising candidates have been proposed as active species for the negative compartment, while potassium ferrocyanide (K 4 Fe (CN) 6) has been the only choice for the positive one.

Are alkaline zinc-based flow batteries suitable for stationary energy storage applications?

Alkaline zinc-based flow batteries are well suitable for stationary energy storage applications, since they feature the advantages of high safety, high cell voltage and low cost. Currently, many alkaline zinc-based flow batteries have been proposed and developed, e.g., the alkaline zinc-iron flow battery and alkaline zinc—nickel flow battery.

Are alkaline flow batteries safe?

We report an alkaline flow battery based on redox-active organic molecules that are composed entirely of Earth-abundant elements and are nontoxic, nonflammable, and safe for use in residential and commercial environments. The battery operates efficiently with high power density near room temperature.

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.
