中文摘要	A pulsed electrodeposition and heat-treatment process was used to prepare copper-tin alloys for the anode of lithium ion battery. The copper-tin alloy electrodes with the structures of sn/Cu6Sn5/Cu3Sn and Sn/Cu3Sn were obtained by plating tin on a substrate of copper foil followed by an anneal-treatment process at 200 degrees C and 300 degrees C. The surface modification of copper-tin alloy electrode was tried. The improved cycle performances and the relatively low specific capacity are due to the formation of copper-tin alloy phases. The main component of the electrode surface changed from Sn/Cu6Sn5 to Cu/Cu6Sn5 after copper coating followed by heat-treatment. After surface modification, the copper-tin alloy electrode presented a high structure stability in a long cycle term. As a result, the copper-tin alloy anode was obtained with high activity and high stability.
