Abstract Grid‐scale energy storage batteries with electrode materials made from low‐cost, earth‐abundant elements are needed to meet the requirements of sustainable energy systems. Sodium‐ion batteries (SIBs) with iron‐based electrodes offer an attractive combination of low cost, plentiful structural diversity and high stability, making them ideal candidates for grid‐scale energy storage systems. Although various iron‐based cathode and anode materials have been synthesized and evaluated for sodium storage, further improvements are still required in terms of energy/power density and long cyclic stability for commercialization. In this Review, progress in iron‐based electrode materials for SIBs, including oxides, polyanions, ferrocyanides, and sulfides, is briefly summarized. In addition, the reaction mechanisms, electrochemical performance enhancements, structure–composition–performance relationships, merits and drawbacks of iron‐based electrode materials for SIBs are discussed. Such iron‐based electrode materials will be competitive and attractive electrodes for next‐generation energy storage devices.
