This enables the use of mixed Zn-Fe electrolytes and microporous separators in place of expensive ion-exchange membranes. Considering the low-cost materials and simple design, zinc-iron chloride flow batteries represent a promising new approach in grid-scale energy storage.
Soc. 164 A1069 DOI 10.1149/2.0591706jes The feasibility of zinc-iron flow batteries using mixed metal ions in mildly acidic chloride electrolytes was investigated. Iron electrodeposition is strongly inhibited in the presence of Zn 2+ and so the deposition and stripping processes at the negative electrode approximate those of normal zinc electrodes.
The optimized parameters of a zinc-iron flow battery are a high flow rate of 50 mL min −1, an asymmetrical structure with a negative electrode of 7 mm and a positive electrode of 10 mm, and high porosity of 0.98.
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. This study provides the requisite experimental data for parameter estimation as well as model validation of ZAFBs.
