摘要
LiV3O8 cathode materials are post-treated by a special emulsion method (termed "EM") and then calcinated at different temperatures. The experimental results show that the structure of these oxides is different from LiV3O8 prepared by the solid-state reaction (acronym "STATE") route, although their starting materials are identical. The EM product prepared at 500 degrees C exhibits a better electrochemical behavior than its counterpart prepared by traditional methods (STATE) or by EM at other temperatures. Its initial discharge capacity is 305 mAh g(-1), and it still maintains 250.2 mAh g(-1) after 100 cycles at 0.2C at the voltage range of 1.8-4.0 V vs. Li/Li+. (C) 2010 Elsevier B.V.
