Abstract
A new hydrothermal process has been developed in this study for synthesizing nanometer LiNiVO4 powder. It was found that when using distilled water as solvent. LiNiVO4 cannot be obtained, and different types of unidentified products are formed. On the other hand, when isopropanol is used, LiNiVO4 powder can be successfully prepared. In comparison with the conventional process, the new hydrothermal process significantly lowers the required reaction temperature and reduces the size of formed particles. In the new process, the required temperature for preparing LiNiVO4 is reduced to 200 °C, and the particle size is decreased to nanometer. The crystallinity of LiNiVO4 can be improved by increasing the hydrothermal temperature and adding ammonia carbonate.
