Nevertheless, iron-air batteries champion the multi-day storage applications with their low cost, inherent safety, and high volumetric energy density (∼200 Wh/L at the pack level).
Almost all have a vanadium-saturated electrolyte--often a mix of vanadium sulfate and sulfuric acid--since vanadium enables the highest known energy density while maintaining long battery life.
For comparison, previous studies of similar iron-based batteries reported degradation of the charge capacity two orders of magnitude higher, over fewer charging cycles.

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.
