The crystalline structure and the electrochemical performance of as-synthesized samples were investigated. The results show that the nanocomposite oxides materials are SnO2-CuO nanocomposites with diameter of about 90nm. The SnO2-CuO nanocomposites exhibit excellent electrochemical performance. After charge-discharged from 30 times to 50 times, the discharge capacity decreases from 254.4 mAh/g to 241.1 mAh/g, and the capacity retention is about 95%. %K SnO2-CuO composite oxides %K precipitation method %K anode material %U http://www.jim.org.cn/fileup/PDF/20100713.pdf
