| 摘 要： | A tin oxide and carbon composite （Sn6O4（OH）4/AG） with a Sn content of 0.15-0.30 was prepared by chemical deposition at normal pressures and temperatures. The structures of the artificial graphite （AG）, the Sn6O4（OH）4, and the Sn6O4（OH）4JAG were analyzed using X-ray diffraction. The electrochemical lithiation was investigated by measuring the galvanostatic charge and discharge ratio. The electrochemical capacities of the three materials during the first discharge were 310 mAh/g （AG）, 616 mAh/g （Sn6O4（OH）4/AG）, and 1090 mAh/g （Sn6O4（oa）4）. The discharge capacity of the Sn6O4（OH）4/AG was larger than the simple sum of the capacities provided by AG and Sn6O4（OH）4 with the same content. The cyclic performance of Sn6O4（OH）4/AG was also better than that of Sn6O4（OH）4 for voltages of 0 to 3 V. The results imply that the interaction between Sn and C in Sn6O4（OH）4/AG is very strong and effectively inhibits the volume expansion of the Sn.
