Abstract
In their Research Article (e202507119), Hyun-Wook Lee et al. reveal that ligand exchange between cyanide and hydroxide in a hexacyanochromate negolyte, driven by coordination disruption of [Cr(CN)6]4−/3−, is a key stability factor. Optimizing the [OH−]/[CN−] ratio stabilizes the redox mediator, enabling long-term performance in aqueous iron-chromium redox flow batteries.
