摘要: 以植物纤维素(滤纸)为模板, 制备了中空SnO2纳米管作为锂离子电池负极材料。通过XRD、SEM、TEM和HR?TEM表征产物的组分、形貌和结构, 表明合成材料是由粒度大小为5~15 nm SnO2粒子组装成的中空纳米管。同时, N2吸附/脱附测试表明此材料为疏松的介孔结构。材料在电流密度100 mA/g 时, 可逆容量稳定在580 mAh/g, 60次循环后容量仍保持为550 mAh/g。制备的中空SnO2纳米管作为锂离子电池负极材料, 具有较高的放电容量和良好的电化学循环性能。

Abstract: An effective method of using cellulosic substances (filter paper) as template was employed to prepare SnO2 nanotubular materials examined as anode for Li-ion battery. According to XRD, SEM, TEM and HR-TEM analysis, the synthesized nanotubular materials retained morphological hierarchy of the filter paper, and each nanotube was composed of nano-sized SnO2 ranged from 5 nm to 15 nm. At the same time, the N2 adsorption/desorption tests show that the materials are mesoporous structure. It exhibits a stable reversible capacity of 580 mAh/g at constant current density of 100 mA/g, and the reversible capacity remains at 550 mAh/g after 60 cycles, showing a high reversible capacity and stable cycle performance as anode for Li-ion battery.

Key words: tin oxide, nanotube, natural cellulose, Li-ion batteries
