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.
Its advantages include long cycle life, modular design, and high safety [7, 8]. The iron-chromium redox flow battery (ICRFB) is a type of redox flow battery that uses the redox reaction between iron and chromium to store and release energy . ICRFBs use relatively inexpensive materials (iron and chromium) to reduce system costs .
The electrolyte in the flow battery is the carrier of energy storage, however, there are few studies on electrolyte for iron-chromium redox flow batteries (ICRFB). The low utilization rate and rapid capacity decay of ICRFB electrolyte have always been a challenging problem.
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.
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.
