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.
A 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.
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.
The Fe (NTHPS)/Fe (CN) 6 RFB exhibits a capacity decay (2.2 %) over 2000 cycles. Alkaline all-iron flow batteries (AIFBs) are highly attractive for large-scale and long-term energy storage due to the abundant availability of raw materials, low cost, inherent safety, and decoupling of capacity and power.
