Iron oxides (FeO x ), such as Fe 2 O 3 and Fe 3 O 4 materials, have attracted much attention because of their rich abundance, low cost, and environmental friendliness. However, FeO x , which is similar to most transition metal oxides, possesses a poor rate capability and cycling life. Thus, FeO x ‐based materials consisting of FeO x , carbon, and metal‐based materials have been widely explored. This article mainly discusses FeO x ‐based materials (Fe 2 O 3 and Fe 3 O 4 ) for electrochemical energy storage applications, including supercapacitors and rechargeable batteries (e.g., lithium‐ion batteries and sodium‐ion batteries). Furthermore, future perspectives and challenges of FeO x ‐based materials for electrochemical energy storage are briefly discussed.
