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 is a zinc bromine flow battery (zbfb)?

Thermal treatment on electrode further increases the energy efficiency to 81.8%. The battery can be operated at a high current density of up to 80 mA cm −2. The zinc bromine flow battery (ZBFB) is regarded as one of the most promising candidates for large-scale energy storage attributed to its high energy density and low cost.

Are aqueous zinc-bromine single-flow batteries viable?

Learn more. Aqueous zinc-bromine single-flow batteries (ZBSFBs) are highly promising for distributed energy storage systems due to their safety, low cost, and relatively high energy density. However, the limited operational lifespan of ZBSFBs poses a significant barrier to their large-scale commercial viability.

What is the power density of a zbfb battery?

The ZBFB delivers a peak power density of 1.363 W cm −2 at room temperature. The ZBFB stably runs over 1200 cycles (∼710 h) at 200 mA cm −2 and 60 mAh cm −2. Zinc-bromine flow batteries (ZBFBs) offer great potential for large-scale energy storage owing to the inherent high energy density and low cost.

Can a membrane-free zinc bromine static battery perform better?

Recently, Liu et al. introduced an alternative type of membrane-free zinc bromine static battery (Figure 11C). The authors proposed the use of different concentration of electrolytes for this research and a highly concentrated electrolyte showed better performance in the presence of a membrane.
