Abstract:Li-ion battery anode material LiV308 was prepared by hydrothermal reaction method. XRD, FT-IR and SEM were carried out to study the structure and morphology of the samples. The galvanostatic charge-discharge technique was used to test the electrochemical performance. The results indicated that the as-prepared LiV308 sample was made up of rod-like particles with about 0.5~μtm in diameter and 1-3μm in length. The initial discharge capacity was 276mAh/g. The electrochemical tests showed that the LiV308 sample had high specific discharge capacity and good cycle performance.
Keywords:Lithium vanadate  Lithium ion battery  Electrode material  Hydrothermal method
