FeP is a promising insertion-conversion electrode material. It has been demonstrated that this material exhibits several noteworthy physicochemical properties, including a high theoretical capacity, low cost, and good mechanical and thermal stability. Furthermore, its low insertion potential and high theoretical capacity of up to 926 mA h g have attracted the attention of researchers as a potential electrode material for alkali metal ion batteries (AMIB). However, the material also exhibits certain disadvantages, including a considerable voltage hysteresis, a substantial volume change, and suboptimal reaction kinetics, resulting in a relatively low-rate capacity and accelerated capacity decay. However, some effective strategies such as composite, doping, and nanostructuring have shown promising applications. Here we present a timely and systematic review of the latest research and significant advances in FeP and its composites, covering synthesis, electrode design, and applications (especially in advanced lithium/sodium/potassium ion batteries) and their reaction mechanisms. Consequently, further modifications have been devised for using iron phosphide composites as anode materials for alkali metal ion batteries (AMIB). The continued innovation of FeP-based anodes demonstrates promise for their utilization in large-scale energy storage applications, including grid storage and electric vehicles. Furthermore, there is an aspiration to encourage the ongoing advancement of FeP anode materials for the development of advanced rechargeable ion batteries.
FeP是一种很有前景的嵌入-转换电极材料。已证明这种材料具有几个值得注意的物理化学性质，包括高理论容量、低成本以及良好的机械和热稳定性。此外，其低嵌入电位和高达926 mA h g的高理论容量作为碱金属离子电池（AMIB）的潜在电极材料引起了研究人员的关注。然而，该材料也存在某些缺点，包括相当大的电压滞后、大量的体积变化以及次优的反应动力学，导致倍率性能相对较低和容量加速衰减。然而，一些有效的策略如复合、掺杂和纳米结构化已显示出有前景的应用。在此，我们及时且系统地综述了FeP及其复合材料的最新研究和重大进展，涵盖合成、电极设计以及应用（特别是在先进的锂/钠/钾离子电池中）及其反应机制。因此，已设计出进一步的改性方法以将磷化铁复合材料用作碱金属离子电池（AMIB）的负极材料。基于FeP的负极的持续创新表明其在大规模储能应用（包括电网储能和电动汽车）中的应用具有前景。此外，期望鼓励FeP负极材料不断进步以推动先进的可充电离子电池的发展。
