Porous LiNiVO4 powder was synthesized via solution combustion synthesis method using lithium nitrate, nickel nitrate, ammonium metavanadate and citric acid as raw materials. Thermogravimetry (TG) and differential scanning calorimetry (DSC), X-ray diffraction (XRD), Fourier-transform infrared (FT-IR) spectroscopy and transmission electron microscopy (TEM) were used to evaluate the structures and morphologies of samples. The results show that the calcination temperature has significant effect on the crystallinity and morphologies. Pure LiNiVO4 flaky nanoparticles with a mean particle size around 20 nm can be readily prepared by calcining the precursor in air at 500 degrees C for 2 h. As a cathode material for lithium-ion batteries, the porous LiNiVO4 powder exhibits a good structural reversibility.
