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.
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 zinc–bromine rechargeable batteries suitable for stationary energy storage applications?
Zinc–bromine rechargeable batteries are a promising candidate for stationary energy storage applications due to their non-flammable electrolyte, high cycle life, high energy density and low material cost. Different structures of ZBRBs have been proposed and developed over time, from static (non-flow) to flowing electrolytes.
What is the energy density of zinc-bromine and Zn-vanadium batteries?
The energy densities for zinc-bromine and Zn-vanadium battery are 282 and 56 Wh/L catholyte, respectively (fig. S14). Since we used single-side flow batteries here, which only flow the anolyte, the high discharge of depth was achieved in all AZFB systems (fig. S17).
Are aqueous zinc-bromine flow batteries reversible?
Aqueous zinc-bromine flow batteries show promise for grid storage but suffer from zinc dendrite growth and hydrogen evolution reaction. Here, authors develop a reversible carbon felt electrode with Pb nanoparticles to suppress these issues, improving battery performance and cycle stability.
Why is a zinc-bromine battery a hybrid redox flow battery?
The zinc-bromine battery is a hybrid redox flow battery, because much of the energy is stored by plating zinc metal as a solid onto the anode plates in the electrochemical stack during charge.
