Abstract

Lithium vanadium tetroxide (Li₃VO₄) anode material has been synthesized by a fast sol-gel method based on spontaneous chemical reactions. The crystal structures, surface morphologies and electrochemical performances of the Li₃VO₄ samples calcined at different temperatures are investigated. In the potential range of 0.02-3.0 V, the sample sintered at 600 °C shows the highest initial charge capacities of 276.2 mAh g^-1, 258.4 mAh g^-1, 201.4 mAh g^-1, at 0.1 C, 0.2 C and 0.5 C, respectively. After 50 cycles, the charge capacities still retains 310.5 mAh g^-1, 278.1 mAh g^-1 and 222.4 mAh g^-1 at 0.1 C, 0.2 C and 0.5 C, respectively. It shows fast sol-gel method is promising in synthesize stable Li₃VO₄ for EV or HEV applications.
