摘要：

A Sn-Co-C composite was prepared by a polymer-pyrolysis route followed with ball milling. The structural and morphological features of the Sn-Co-C composite were characterized by powder X-ray diffraction and scanning electron microscope. The experimental results revealed that the Sn-Co-C composite can deliver a high reversible capacity of 486 mAh g(-1) after 40th cycle. This suggests that the polymer-pyrolysis method provides a possible alternative for preparation of the alloy anode for lithium-ion batteries. (C) 2008 Elsevier B.V. All rights reserved.
