Tin and tin compounds are perceived as promising next-generation lithium (sodium)-ion batteries anodes because of their high theoretical capacity, low cost and proper working potentials. However, their practical applications are severely hampered by huge volume changes during Li (Na) insertion and extraction processes, which could lead to a vast irreversible capacity loss and short cycle life. The significance of morphology design and synergic effects-through combining compatible compounds and/or metals together-on electrochemical properties are analyzed to circumvent these problems. In this review, recent progress and understanding of tin and tin compounds used in lithium (sodium)-ion batteries have been summarized and related approaches to optimize electrochemical performance are also pointed out. Superiorities and intrinsic flaws of the above-mentioned materials that can affect electrochemical performance are discussed, aiming to provide a comprehensive understanding of tin and tin compounds in lithium(sodium)-ion batteries.
由于锡及其化合物具有较高的理论容量、低成本和合适的工作电位，它们被视为下一代锂（钠）离子电池有前景的负极材料。然而，在锂（钠）嵌入和脱出过程中，巨大的体积变化严重阻碍了它们的实际应用，这可能导致大量不可逆容量损失和短循环寿命。分析了通过将相容的化合物和/或金属结合在一起的形态设计和协同效应对电化学性能的重要性，以规避这些问题。在这篇综述中，总结了锂（钠）离子电池中使用的锡及其化合物的最新进展和认识，并指出了优化电化学性能的相关方法。讨论了上述材料影响电化学性能的优势和固有缺陷，旨在全面了解锂（钠）离子电池中的锡及其化合物。
