Abstract

LiNiVO4 nano-crystallites were prepared by the polymerized complex method using Li2CO3, Ni(CH3COO)2·4H2O and NH4VO3 as starting reagents and malic acid as a complexing agent. With the subsequent calcination at 450 °C, the powder analyzed by XRD, FTIR, Raman, electron diffraction, SEM and TEM techniques was found to be inverse spinel LiNiVO4 with ∼20 nm in diameter. TGA shows continuous weight loss at 40–450 °C due to the evaporation and decomposition processes. Above 450 °C, weight percent tended to be constant. In addition, formation mechanism of the purified LiNiVO4 was proposed to relate with the experimental results.
