摘要：

With LiOH center dot H2O and NH4VO3 as the identical starting materials, several diverse methods were introduced to prepare lithiated vanadium oxides LiV3O8 which are promising as the cathode material for secondary lithium batteries. The crystalline phase were characterised by powder X-ray diffraction. The electrochemical properties of prepared samples were systematically investigated and compared. The maximal initial specific discharge capacity belongs to the material produced by hydrothermal route which can attain 338 mAh.g(-1) at a current density of 0.2C. While the sol-gel route produced sample exhibit the best cycling behaviour among these lithium trivanadate, which kept 93% of its initial capacity as 209 mAh.g(-1) after 20 cycles.
