We reported a new method to prepare LixTiS2 (0 <= x <= 1) at 600 degrees C in sealed tube using Li2S as lithium source. The LixTiS2 samples were characterized by powder X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, and differential thermal analysis. The variations of the lattice parameters with lithium content x in LixTiS(2) were determined by X-ray powder diffraction analysis for both 1T and 3R phases. The phase transition between low-temperature 1T phase and high-temperature 3R phase was confirmed by the powder X-ray diffraction analysis. Based on the differential thermal analysis and X-ray diffraction results, a schematic phase diagram of the LixTiS(2) system has been constructed, providing a guideline to synthesize LixTiS(2) in IT structure or 3R structure.
