新兴的钠离子电池（SIBs）因其成本低、资源丰富等优点而受到广泛关注。然而，开发出具有优异倍率性能和良好循环性能的阳极材料仍然是一个重大挑战。与插入型阳极材料相比，转换型阳极材料由于其高比容量和低成本而具有很大的潜力。本文对纳米结构转换型sib负极材料的最新研究进展进行了综述。介绍了相应的合成方法、钠存储性能、电化学机理、晶体结构研究的先进技术以及高性能电池的优化策略。最后，对转换型负极材料在储能领域的未来发展提出了挑战和展望。
Emerging sodium‐ion batteries (SIBs) have attracted a great attention as promising energy storage devices because of their low cost and resource abundance. Nevertheless, it is still a major challenge to develop anode materials with outstanding rate capability and excellent cycling performance. Compared to intercalation‐type anode materials, conversion‐type anode materials are very potential due to their high specific capacity and low cost. A new insight and summary on the recent research advances on nanostructured conversion‐type anode materials for SIBs is provided herein. The corresponding synthesis methods, sodium storage properties, electrochemical mechanisms, advanced techniques on studying the crystal structures, and optimization strategies for high‐performance batteries are presented. Finally, the remaining challenges and perspectives for the future development of conversion‐type anode materials in the energy storage fields are proposed.
