Abstract

A novel technique was employed to preparing LiV3O8 in which LiOH·H2O and NH4VO3 were used as the raw materials. The structure, morphology and properties of the sample were investigated by XRD, TGA/DTA, TEM, charge-discharge and CV. The results of XRD and TEM show that different calcining temperatures result in different structure and morphology, which lead to different discharge capacities. The specific discharge capacity of the sample calcined at 300℃ for 6h, in the range of 1.8--3.8V, is up to 342mAh/g in the first cycle. The capacity of the sampl is decreased with the increase of calcining temperatures.
