Free QuoteA new iron-based aqueous flow battery shows promise for grid energy storage applications. A commonplace chemical used in water treatment facilities has been repurposed for large-scale energy storage in a new battery design by researchers at the Department of Energy's Pacific Northwest National Laboratory.
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.
The rapid advancement of flow batteries offers a promising pathway to addressing global energy and environmental challenges. Among them, iron-based aqueous redox flow batteries (ARFBs) are a compelling choice for future energy storage systems due to their excellent safety, cost-effectiveness and scalability.
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.
Despite extensive research efforts in electrolyte optimization, commercial all-iron flow batteries, according to the ESS Energy Center datasheet, still rely on a relatively simple FeCl 2 -based electrolyte composition, with an expected lifespan of 25 years.
In 2024, Yang et al. proposed a highly soluble, polar and electron-donating additive, N,N -dimethylacetamide (DMAc), for operating all-iron flow batteries at low temperatures . In an aqueous environment below −10°C, smooth and compact iron deposition was demonstrated on carbon felt (CF), indicating excellent Fe 2+ /Fe 0 reversibility.
