Abstract:	The copper-doped LiV₃O₈ was first prepared by mixing copper powder with solid-state synthesized LiV₃O₈ in distilled water. The electrochemical performance of the copper-doped LiV₃O₈ 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 LiV₃O₈ could be easily prepared by a simple addition of the doping metal.

Keywords:	Lithium trivanadate Copper lithium trivanadate Composite materials Crystal structure Electrochemical performance
