Abstract
A novel soft solution process has been used to prepare LiCoVO 4 by reacting Co(CH 3CH 2COO) 2, Li 2CO 3, NH 4VO 3 and citric acid. LiCoVO 4 powders were successfully prepared at as low as 450 °C in 4 h. Compared to the solid-state reaction processes, the soft solution process greatly reduced the temperature and the time for preparing LiCoVO 4. The inverse spinel structure and high crystallinity of the synthesized product has been confirmed by X-ray diffraction. Thermal analysis proves that the phase formation of the compound occurs at about 450 °C. The results of the IR investigations show that the band located at 820 cm −1 corresponds to the stretching vibration mode of VO 4 tetrahedron with the A 1 symmetry. SEM examination reveals a spherical grain distribution, the average particle size being typically lower than 1 μm. The quantitative result from ICP-AES analysis is Li 0.967Co 0.994VO 4.
