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].
Can zinc-bromine flow batteries be used in aqueous electrolyte?
Zinc-bromine flow batteries (ZBFBs) exhibit considerable potential for future applications due to their high theoretical energy density (435 Wh kg −1), high open-circuit potential (1.82 V), and use of aqueous electrolyte.
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.
Is there a non flow Zinc Bromine battery without a membrane?
Lee et al. demonstrated a non-flow zinc bromine battery without a membrane. The nitrogen (N)-doped microporous graphene felt (NGF) was used as the positive electrode (Figure 11A,B).
Does PNSC increase ion diffusion rate in zinc–bromine flow batteries?
In addition, the highly porous (∼ m 2 /g) PNSC substantially increased the ion diffusion rate within the electrode framework which led the voltage efficiency of 83 % and energy efficiency of 82 % at 80 mA cm −2.
