Technical FAQs 4

What are zinc-bromine flow batteries?

In particular, zinc-bromine flow batteries (ZBFBs) have attracted considerable interest due to the high theoretical energy density of up to 440 Wh kg−1 and use of low-cost and abundant active materials [10, 11].

Are aqueous zinc–bromine batteries a viable solution for next-generation energy storage?

Aqueous zinc–bromine batteries (ZBBs) have attracted considerable interest as a viable solution for next-generation energy storage, due to their high theoretical energy density, material abundance, and inherent safety. In contrast to conventional aqueous batteries constrained by sluggish ion diffusion throug

Are zinc-bromine flow batteries suitable for large-scale energy storage?

Zinc-bromine flow batteries (ZBFBs) offer great potential for large-scale energy storage owing to the inherent high energy density and low cost. However, practical applications of this technology are hindered by low power density and short cycle life, mainly due to large polarization and non-uniform zinc deposition.

Do zinc–bromine redox flow batteries use a bromine complexing agent?

Study of Bromine Complexing Agents in ZBFBs Zinc–bromine redox flow batteries (ZBFBs) should use a bromine complexing agent (BCA) as an additive for bromine stability, as shown below.
