Iron-chromium redox flow battery was invented by Dr. Larry Thaller's group in NASA more than 45 years ago. The unique advantages for this system are the abundance of Fe and Cr resources on earth and its low energy storage cost. Even for a mixed Fe/Cr system, the electrolyte cost is still less than 10$/kWh.
The current density of current iron–chromium flow batteries is relatively low, and the system output efficiency is about 70–75 %. Current developers are working on reducing cost and enhancing reliability, thus ICRFB systems have the potential to be very cost-effective at the MW-MWh scale.
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.
