摘要：

The copper-doped LiV(3)O(8) was first prepared by mixing copper powder with solid-state synthesized LiV(3)O(8) in distilled water. The electrochemical performance of the copper-doped LiV(3)O(8) was compared with that of the undoped one. It was found that the electrochemical performance of the copper-doped sample is significantly improved, with an initial capacity of 265.0 mAh/g and a stabilized capacity of 227.7 mAh/g after 100 cycles. It indicates that the copper-doped LiV(3)O(8) could be easily prepared by a simple addition of the doping metal. (C) 2008 Elsevier B.V. All rights reserved.
