英文摘要：

The anode materials of Sn-Co-M-C （M--Zn, Fe） composites were prepared by carbothermal re- duction method from metal oxides and sucrose in N2 atmosphere. Their structural and electrochemical proper-ties were studied by XRD, SEM and charge-discharge test. Among them, the Sn-Co-Zn-C composite showed higher specific capacity and good cycle performance. The initial special discharge capacity of 571 mAh·g^-1 could be obtained, while 369 mAh·g^-1 was still kept after 45 cycles.
