摘要:: 随着低碳环保的生活方式不断深入人心，人们对能源储存器件的需求日益增加。锂离子电池由于具有较高的工作电压、较高的能量密度和良好的循环寿命，逐渐占领了二次能源储存市场。当然，锂离子电池也面临着自身的问题，如锂资源储量少、开采难度大而导致的锂离子电池成本高。钠离子电池具有与锂离子电池相似的电化学性质，且钠盐资源丰富，近年来受到了研究者们的广泛关注。在整个电池中，电极材料的作用尤为重要，决定了整个电池的循环寿命。铁基电极材料具有丰富的原材料资源、价格低廉、安全无污染，因此成为了最合适的一类电极材料。然而，铁基电极材料的电化学性能还有待进一步改善。通过设计合适的纳米结构以及发展简易的金属有机框架化合物衍生的方法，制备了一系列铁基电极材料，并用于锂、钠离子电池，取得了不错的电化学性能。综述了近年来研究者们和作者课题组制备的铁基电极材料在锂、钠离子电池上的研究进展。

Abstract:: 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.
