Along with the increasing demand for low CO2 emission, renewable and environment friendly power sources, the traditional fossil fuel will be inevitably replaced by the secondary batteries or other energy storage device. Lithium-ion batteries (LIBs) have now dominated the commercial market of energy storage device owing to the considerable work voltage, high energy density and long cycle life. However, their further extensive application is greatly hampered by the limited lithium resource, difficulty of mining and high cost. Sodium-ion batteries (SIBs) with abundant natural resources and low cost have attracted researchers' extensive attention. The functions of electrode materials determine the cycling-performance of electrochemical cell. Iron-based materials with high theoretical capacities, abundant natural resources, low cost, safety and no pollution, are suitable as electrode materials for LIBs and SIBs. However 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 frameworks(MOFs)-derived route has been exploited. And a series of iron-base electrode materials have been synthesized, which have achieved excellent electrochemical performance. This paper reviews recent progress of nanostructured iron-based electrode materials used for LIBs/SIBs.
