Iron chromium battery is the earliest liquid flow battery technology that emerged. It was included in NASA''s research program as early as 1974 and received support from the US Department of Energy. In 1978, iron chromium batteries were successfully developed with Fe2+/Fe3+and Cr2+/Cr3+pairs as positive and negative active materials
The geologic sources of chromium are essentially mixtures of spinels of the ideal form RO·R 2 O 3 (e.g., chromite is FeO·Cr 2 O 3), although a more accurate representation of an ore source would be (Mg,Fe)Cr 2 O 4 with silica and alumina gangue materials. The refining processes for chromium metal have been thermodynamically defined by their spinel origins.

Thanks to the chemical characteristics of the iron and chromium ions in the electrolyte, the battery can store 6,000 kilowatt-hours of electricity for six hours. A company statement says that iron-chromium flow batteries can be recharged using renewable energy sources like wind and solar energy and discharged during high energy demand.
Iron–chromium flow battery (ICFB) is one of the most promising technologies for energy storage systems, while the parasitic hydrogen evolution reaction (HER) during the negative process remains a critical issue for the long-term operation. To solve this issue, In³⁺ is firstly used as the additive to improve the stability and performance of ICFB.
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 .
Suppressing the undesirable decomposition of the chromium (II) chloride Cr (II) complex used in the battery is the crucial step for avoiding these issues during the electrochemical cycling of redox flow batteries, thus facilitating a stable and fast redox reaction.
Most importantly, iron-chromium flow battery with the optimized electrolyte presents excellent battery efficiency (coulombic efficiency: 97.4%; energy efficiency: 81.5%) when the operating current density is high up to 120 mA cm⁻².
During the charging process, the negative electrode has a side reaction: hydrogen evolution reaction (HER), while a part of Cr 3+ cannot be reduced [29, 30]. However, Fe 2+ in the positive electrolyte can react completely. When the molar ratio of iron to chromium is 1:1, the active substances of the positive and negative reactions do not match.
