dc.description.abstractSilicon nanowires (Si NWs) with copper-coating as high capacity and improved cycle-life anode for lithium-ion batteries have been successfully prepared by chemical vapor deposition and magnetron sputtering methods. The morphology, structure, composition as well as the electrochemical performance of copper-coated Si NWs is characterized in detail. The results indicate that the copper-coated Si NWs electrodes show an initial coulombic efficiency of 90.3% when cycling between 0.02V and 2.0 V (versus Li/Li(+)) at a current density of 210 mA g(-1). The copper-coated Si NWs electrodes exhibit a capacity as high as 2700 mAh g(-1) at the first cycle. They also show a good capacity retention and excellent rate capability compared with pristine and carbon-coated Si NWs. (C) 2011 Elsevier B.V. All rights reserved.zh_CN
