With the fast-growing demand for green and safe energy sources, rechargeable ion batteries have gradually occupied the major current market of energy storage devices due to their advantages of high capacities, long cycling life, superior rate ability, and so on. Metallic Sn-based anodes are perceived as one of the most promising alternatives to the conventional graphite anode and have attracted great attention due to the high theoretical capacities of Sn in both lithium-ion batteries (LIBs) (994 mA h g) and sodium-ion batteries (847 mA h g). Though Sony has used Sn-Co-C nanocomposites as its commercial LIB anodes, to develop even better batteries using metallic Sn-based anodes there are still two main obstacles that must be overcome: poor cycling stability and low coulombic efficiency. In this review, the latest and most outstanding developments in metallic Sn-based anodes for LIBs and SIBs are summarized. And it covers the modification strategies including size control, alloying, and structure design to effectually improve the electrochemical properties. The superiorities and limitations are analyzed and discussed, aiming to provide an in-depth understanding of the theoretical works and practical developments of metallic Sn-based anode materials.
随着对绿色安全能源需求的快速增长，可充电离子电池因其高容量、长循环寿命、优异倍率性能等优点，逐渐占据了当前储能设备的主要市场。金属锡基负极被认为是传统石墨负极最有前途的替代品之一，由于锡在锂离子电池（LIBs）（994 mA h g）和钠离子电池（847 mA h g）中都具有较高的理论容量，因此受到了广泛关注。尽管索尼已将锡钴碳纳米复合材料用作其商用LIB负极，但要开发出使用金属锡基负极的更好电池，仍有两个主要障碍必须克服：循环稳定性差和库仑效率低。在这篇综述中，总结了用于LIBs和SIBs的金属锡基负极的最新和最突出的进展。并且涵盖了尺寸控制、合金化和结构设计等改性策略，以有效改善电化学性能。分析和讨论了其优势和局限性，旨在深入了解金属锡基负极材料的理论研究和实际进展。
