摘　　要：锡基材料作为钠离子电池的负极材料具有较高的理论比容量,成为钠离子电池负极材料的研究重点。然而,锡基负极材料在钠离子嵌入和脱出过程中有巨大的体积变化,导致较差的电池循环性能。简要介绍了锡基纳米复合材料作为钠离子电池负极材料的研究进展。阐述了不同形貌的锡基氧化物和硫化物复合材料的制备方法及其电化学性能,并讨论了该电极材料面临的问题以及主要解决措施等。Due to the remarkable theoretical capacity, Sn-based anode materials for Na-ion batteries（NIBs）, have received extensive interests. However, the sodiation/desodiation process often accompanies with large volume expansion and further causes pulverization, leading to the poor cycle life of NIBs. Most recent progress of Sn-based anode materials for NIBs, including the discovery of new electrode materials, preparing methods, morphology and their Na storage mechanisms, were briefly reviewed. In addition, the efforts to enhance the electrochemical properties of NIB electrode materials as well as the challenges and perspectives involving these materials were discussed.
