摘要

LiV₃O₈ has been synthesized by an improved spray-drying method which is dozens of times faster than the conventional route. The as-obtained powder was characterized by XRD, indicating this material was almost pure LiV₃O₈. The electrochemical performance of LiV₃O₈ as the cathode material was investigated, which demonstrated that as-prepared LiV₃O₈ exhibited as high as 340.2 mA h g^鈭?#xA0;1 discharge capacity in first cycle at current density of 25 mA g^鈭?#xA0;1; moreover, after 100 cycles at the current density of 125 mA g^鈭?#xA0;1, it still maintained a high discharge capacity of 241.8 mAh g^鈭?#xA0;1, suggesting its promising application as the cathode material for Li-ion batteries.
