摘要:

由于资源丰富、价格低廉以及较高比容量,铁(Fe)基材料在钠离子电池负极材料中具有广泛应用前景。然而,Fe基负极材料存在电导率低和在充放电过程中发生的较大体积变化等问题,导致其倍率性能和循环稳定性较差,严重限制了其在钠离子电池领域的大规模应用。构建具有异质结构的Fe基电极材料对提高电导率、增强动力学特性、以及缓解循环过程中由于较大体积变化引起的结构破坏至关重要,从而显著提高Fe基电极材料的综合电化学性能。本文详细综述了具有异质结构的Fe基负极材料在钠离子电池中的研究进展,重点阐述了异质结构Fe基电极材料的合成方法、表征手段和储能机制。同时,对异质结构Fe基氧化物、硫化物、磷化物、硒化物负极材料以及双阴离子Fe基负极材料的储钠特性、改性策略和强化机制等最新研究进展进行归纳。最后,对Fe基异质结构负极材料面临的挑战和发展前景进行总结,以期促进Fe基异质结构钠离子电池负极材料的快速发展和实际应用。

Abstract:

Sodium ion batteries (SIBs), characterized by high energy density, prolonged cycle life, and cost-effectiveness, have garnered substantial attention as scalable energy storage devices. However, the primary challenge facing SIBs is the identification of suitable electrode materials capable of accommodating sodium ions reversibly and sustainably. To transition SIBs from the experimental stage to practical applications, the identification of electrode materials exhibiting satisfactory electrochemical performance is imperative. Iron (Fe), as a widely utilized metal element, exhibits considerable potential for application as anode materials in SIBs due to its abundance, cost-effectiveness, and high specific capacity. Nonetheless, Fe-based electrode materials suffer from low conductivity and significant volume changes during charge and discharge processes, leading to poor rate performance and cyclic stability, thereby restricting their widespread application in SIBs. Various modification strategies, such as nanosizing electrode materials, heteroatom doping, heterostructure construction, and combination with fast ion conductors, have been reported to address these challenges. Importantly, engineering Fe-based electrode materials with heterogeneous structures, integrating two or more components via van der Waals forces or chemical bonds, is crucial for creating intricate heterogeneous interfaces. These interfaces generate self-built electric fields that expedite ion transport, enhance reaction kinetics, and mitigate structural damage due to volume changes during cycling, thereby significantly improving the overall electrochemical performance of Fe-based materials in SIBs. Given the rapid advancements in the utilization of Fe-based materials in SIBs, a comprehensive review is necessary to not only summarize recent progress but also provide insight and guidance on their application in SIBs. This review offers a detailed overview of the research progress on Fe-based anode materials with heterostructure in SIBs. Emphasis is placed on synthesis methods, characterization techniques, and energy storage mechanisms of heterostructure Fe-based electrode materials. Additionally, the sodium ion storage characteristics, modification strategies, and strengthening mechanisms of Fe-based materials, including Fe-based oxides, sulfides, phosphides, selenides, as well as dual-anion Fe-based anode materials, are summarized. Finally, the remaining challenges and future development prospects of Fe-based heterostructure anode materials are discussed, aiming to promote the rapid development and practical application of these materials for SIBs.
