Iron-based flow batteries designed for large-scale energy storage have been around since the 1980s, and some are now commercially available. What makes this battery different is that it stores energy in a unique liquid chemical formula that combines charged iron with a neutral-pH phosphate-based liquid electrolyte, or energy carrier.

All-iron flow batteries are a safer alternative to other metals frequently used in electrochemical energy storage devices, such as lithium. While lithium hydrates are toxic, flammable, react violently with water and corrode in air, iron is a relatively non-toxic alternative that is only slightly reactive with water and air.

Based on the above results, we proposed that the attenuation mechanism in alkaline all-iron ions RFBs is originated from the •OH mediated side reaction between Fe (CN) 63− and free ligands. As shown in Fig. 4c, Fe (CN) 63− oxidize OH − into the strong oxidizing agents of •OH and themselves are reduced into Fe (CN) 64−.
