Among the above-mentioned flow batteries, the zinc-based flow batteries that leverage the plating-stripping process of the zinc redox couples in the anode are very promising for distributed energy storage because of their attractive features of high safety, high energy density, and low cost .
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.
With super high energy density, long cycling life, and a simple structure, a ZISFB becomes a very promising candidate for large scale energy storage and even for power batteries. A zinc–iodine single flow battery (ZISFB) with super high energy density, efficiency and stability was designed and presented for the first time.
The history of zinc-based flow batteries is longer than that of the vanadium flow battery but has only a handful of demonstration systems. The currently available demo and application for zinc-based flow batteries are zinc-bromine flow batteries, alkaline zinc-iron flow batteries, and alkaline zinc-nickel flow batteries.
However, because of the intermittent nature of these energy sources, efficient energy storage systems are needed. In this regard, zinc-air flow batteries (ZAFBs) are seen as having the capability to fulfill this function. In flow batteries, the electrolyte is stored in external tanks and circulated through the cell.
A zinc–iodine single flow battery (ZISFB) with super high energy density, efficiency and stability was designed and presented for the first time. In this design, an electrolyte with very high concentration (7.5 M KI and 3.75 M ZnBr2) was sealed at the positive side. Thanks to the high solubility of KI, it fu

Energilagring bliver i højere grad en nødvendighed i vores dagligdag og i stadig større grad i den nærmeste fremtid. Hvad enten der skal strømforsynes til køretøjer eller telefoner, for at anvende energien, der kommer fra vedvarende energikilder selv på en vindstille dag, overskyet dag, eller fra en reserve lagring, bliver vi mere og mere afhængige af batterier.
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].
