摘　　要：锡基氧化物以其高的理论比容量、低成本、低毒性、宽广的实用性成为理想的锂离子电池负极材料,然而在其充放电过程中体积变化较大,影响了电极的循环性能。从锡基氧化物的储锂机理、制备方法和改善锡基氧化物电化学性能的研究等方面,分析总结了近年来锡基氧化物负极材料在结构和形貌、掺杂、制备锡基氧化物复合材料方面的最新进展,展望了其发展趋势。SnO2-based structured materials have been attracting intensive research attention as high-capacity cathodes for a variety of reasons,including their high theoretical capacity,low cost,low toxicity,and widespread availability.However,the large volume expansion-contraction in the process of charge and discharge limits the cycling life of electrodes.The recent improvement,such as electrode microstructure and morphology,doping and composite cathodes materials were reviewed from the aspects of mechanisms of lithium insertion,synthesis methods and electrochemical performances.The trends of research and development are highlighted.
