Under the increasing demand for low CO2 emission, renewable and environment friendliness power sources, the traditional fossil fuel will be inevitable replaced by the secondary batteries or other energy storage device. Li-ion batteries (LIBs) have now dominated the commercial market of energy storage device owing to the considerable work voltage and long cycle life. However their further extensive application is greatly hampered by the limited lithium resource. Na-ion batteries (SIBs) with the nature abundance resources and low cost have attracted researchers’ extensive attention. Iron-based materials with high theoretical capacities and nature abundance resources are suitable as electrode materials for LIBs and SIBs, and the development of well-defined iron-based electrode materials with high specific capacity and long-cycling performance for LIBs and SIBs is still a crucial issue. Our group have developed a series of nanostructured iron-based materials for LIBs/SIBs, specially, a facile metal organic framework (MOF)-derived route has been exploited. This manuscript reviews recent progress of nanostructured iron-based electrode materials used for LIBs/SIBs.
