4 FAQs about Ion movement in zinc-bromine flow batteries

Are zinc–bromine flow batteries good for energy storage?

Zinc–bromine flow batteries (ZBFBs) hold great promise for grid-scale energy storage owing to their high theoretical energy density and cost-effectiveness. However, conventional ZBFBs suffer from inhomogeneous zinc deposition and sluggish Br2/Br–

Are aqueous zinc-bromine flow batteries durable?

Aqueous zinc-bromine flow batteries (ZBFBs) are among the most appealing technologies for large-scale stationary energy storage due to their scalability, cost-effectiveness, safety and sustainability. However, their long-term durability is challenged by issues like the hydrogen evolution reaction (HER) and dendritic zinc electroplating.

Is there a single flow Zinc-Bromine battery with improved energy density?

A novel single flow zinc-bromine battery with improved energy density. J. Power Sources 235, 1–4 (2013). Jiang, H. R., Wu, M. C., Ren, Y. X., Shyy, W. & Zhao, T. S. Towards a uniform distribution of zinc in the negative electrode for zinc bromine flow batteries. Appl. Energy 213, 366–374 (2018).

What is a non-flow electrolyte in a zinc–bromine battery?

In the early stage of zinc–bromine batteries, electrodes were immersed in a non-flowing solution of zinc–bromide that was developed as a flowing electrolyte over time. Both the zinc–bromine static (non-flow) system and the flow system share the same electrochemistry, albeit with different features and limitations.
