Abstract:

Nanocomposite oxides materials (SnO2-CuO) as anode materials for lithium-ion batteries were synthesized via precipitation method. 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%.

Key words: SnO2-CuO composite oxides, precipitation method, anode material
