摘要:

隨著低碳環保的生活方式不斷深入人心，人們對能源儲存器件的需求日益增加。鋰離子電池由于具有較高的工作電壓、較高的能量密度和良好的循環壽命，逐漸占領了二次能源儲存市場。當然，鋰離子電池也面臨著自身的問題，如鋰資源儲量少、開采難度大而導致的鋰離子電池成本高。鈉離子電池具有與鋰離子電池相似的電化學性質，且鈉鹽資源豐富，近年來受到了研究者們的廣泛關注。在整個電池中，電極材料的作用尤為重要，決定了整個電池的循環壽命。鐵基電極材料具有豐富的原材料資源、價格低廉、安全無污染，因此成為了最合適的一類電極材料。然而，鐵基電極材料的電化學性能還有待進一步改善。通過設計合適的納米結構以及發展簡易的金屬有機框架化合物衍生的方法，制備了一系列鐵基電極材料，并用于鋰、鈉離子電池，取得了不錯的電化學性能。綜述了近年來研究者們和作者課題組制備的鐵基電極材料在鋰、鈉離子電池上的研究進展。

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.
