Large scale energy storage is a key technology to solve the non-steady state problem of renewable energy. All vanadium redox flow battery is one of the promising large scale energy storage technologies. However, the high cost restricts its further development which is mainly influenced by the price of vanadium. Iron compounds are ideal active materials for flow batteries because of its abundant reserves and low price. In this work, based on the existing research about iron based flow batteries, we review the advantages and characteristics of different types of iron based flow batteries, and summarizes the key issues and research progress of various types of iron based flow batteries. We introduce the application situation of iron based flow battery, and prospect its future development direction.
