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 flow batteries suitable for stationary energy storage?
Aqueous zinc-bromine flow batteries (ZBFBs) are one of the most attractive candidates for large-scale stationary energy storage due to their high energy density, intrinsic safety, and low cost. However, the low efficiency and restricted lifespan caused by the bromine shuttling and slow reaction kinetics severely limit their future development.
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.
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 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.
What is the CE and EE of a zbfb battery?
It is found that at 400 mA cm −2, the battery achieves a CE of 98.82 % and an EE of 74.14 %. Remarkably, even at 700 mA cm −2, the CE and EE maintain high values of 98.65 % and 61.51 %, respectively. The polarization curve and power density of the ZBFB are shown in Fig. 6 c.
Why does zif-62/5% MEP have more free bromine ions?
This is because that ZIF-62/5% MEP complexes more free bromine molecules and facilitates participating in the reaction, rather than the bromide ions of MEP getting or losing electrons to enhance the capacity (Figures S13, S14, Supporting Information).
