Iron-based materials with significant physicochemical properties, including high theoretical capacity, low cost and mechanical and thermal stability, have attracted research attention as electrode materials for alkali metal-ion batteries (AMIBs). However, practical implementation of some iron-based materials is impeded by their poor conductivity, large volume change, and irreversible phase transition during electrochemical reactions. In this review we critically assess advances in the chemical synthesis and structural design, together with modification strategies, of iron-based compounds for AMIBs, to obviate these issues. We assess and categorize structural and compositional regulation and its effects on the working mechanisms and electrochemical performances of AMIBs. We establish insight into their applications and determine practical challenges in their development. We provide perspectives on future directions and likely outcomes. We conclude that for boosted electrochemical performance there is a need for better design of structures and compositions to increase ionic/electronic conductivity and the contact area between active materials and electrolytes and to obviate the large volume change and low conductivity. Findings will be of interest and benefit to researchers and manufacturers for sustainable development of advanced rechargeable ion batteries using iron-based electrode materials.
具有显著物理化学性质的铁基材料，包括高理论容量、低成本以及机械和热稳定性，作为碱金属离子电池（AMIBs）的电极材料已引起研究关注。然而，一些铁基材料在实际应用中受到其导电性差、体积变化大以及电化学反应过程中不可逆相变的阻碍。在本综述中，我们批判性地评估了用于AMIBs的铁基化合物在化学合成、结构设计以及改性策略方面的进展，以解决这些问题。我们评估并分类了结构和组成调控及其对AMIBs工作机制和电化学性能的影响。我们深入了解它们的应用，并确定其发展中的实际挑战。我们提供了未来方向和可能成果的观点。我们得出结论，为了提高电化学性能，需要更好地设计结构和组成，以提高离子/电子导电性以及活性材料与电解质之间的接触面积，并避免大体积变化和低导电性。这些发现将对研究人员和制造商在使用铁基电极材料可持续开发先进可充电离子电池方面具有意义和帮助。
