Preparation and Lithium Storage Properties of LiV3O8 as a Cathode Materials

Abstract

Abstract The LiV3O8 cathode materials was successfully synthesized by PEG-assisted freeze drying combination with calcination treatment process. The annealing temperature affected the electrochemical properties of the LiV3O8 cathode materials. The LiV3O8 cathode materials annealed at different temperatures were characterized by X-ray diffraction, Scanning electron microscopy, and Galvanization charge/discharge profile measurement. The results demonstrated that with the increase of sintering temperature, accompanied with the change of the morphology of the nanoparticles to nanorods. The LiV3O8 fabricated at 500 °C (LVO500) showed the high capacity and good rate capability (after 100th, a reversible discharge capacity up to 218 mAh g−1).
