中文摘要：
以氯化亚锡和高岭土为原料，通过醇解，氨解反应，制备了纳米SnO2／高岭土复合材料。利用XRD、TEM测试技术对复合材料进行了表征。结果表明，550℃焙烧后复合材料中的SnO2粒子平均粒径在20nm左右，较纯材料中的SnO2粒子团聚现象减少。将复合材料作为锂离子负极材料进行了研究，与纯氧化锡相比这种复合材料具有较高可逆容量（达741mAh／g），同时循环性能也得到了提高。
英文摘要：
SnO2/kaolin composite was prepared from SnCl2 and kaolin as raw materials by aleoholysis and ammonia. The composite materials were characterized by X-ray diffraction （XRD） and transmission electron microscopy （TEM）. The results showed that the average size of the composite obtained after calcinations at the temperature of 550℃ was about 20nm, Reuniting phenomena of SnO2 of the composite decreased than the pure. The electrochemical properties of SnO2/kaolin composite as anode material for lithium ion batteries were investigated. SnO2/kaolin composite possessed the advantages of higher reversible capacity （more than 741mAh/g）and improved cycle performance.
