Abstract

Li1+xV1-xO2 samples with different ratios of Li/V (1.12 (x = 0.056), 1.17 (x = 0.078), 1.22 (x = 0.1), 1.27 (x = 0.118), and 1.32 (x = 0.138) are synthesized via wet synthesis route followed by a high temperature treatment. As anode materials for lithium-ion batteries, the electrochemical performances of as-synthesized Li1+xV1-xO2 materials are investigated by galvanostatic charge-discharge test. The Li1+xV1-xO2 compound synthesized with the ratio of Li/V = 1.32 possesses the optimal performance, delivering an initial discharge capacity of 183.8 mAh g-1 between 0.005 V and 3 V at a current density of 0.2C, and exhibiting a good cycling stability over 20 cycles. Selection and peer-review under responsibility of the scientific committee of the 7th International Conference on Nanomaterials and Advanced Energy Storage Systems.
