以Sn纳米棒为牺牲模板，采用葡萄糖水热法和碳化法制备了碳包覆SnO 2（SnO 2-C）纳米管。所合成的SnO 2-C纳米管已被用作锂离子电池的负极材料，与纯SnO 2纳米管相比，其表现出改善的循环性能。中空纳米结构与具有良好缓冲效果和高电子传导性的碳基质一起可以负责改善的循环性能。
This paper reports the synthesis of carbon-coated SnO2 (SnO2-C) nanotubes through a simple glucose hydrothermal and subsequent carbonization approach by using Sn nanorods as sacrificial templates. The as-synthesized SnO2-C nanotubes have been applied as anode materials for lithium-ion batteries, which exhibit improved cyclic performance compared to pure SnO2 nanotubes. The hollow nanostructure, together with the carbon matrix which has good buffering effect and high electronic conductivity, can be responsible for the improved cyclic performance.
