Abstract: The compound, lithium trivanadate (LiV 3O 8), was synthesized by the polymer precursor method, using the polymer polyvinylpyrrolidone. The electrochemical performance of LiV 3O 8 was compared with LiV 3O 8 synthesized by the solid state reaction method. The prepared compounds were characterized by X-ray diffraction, scanning electron microscopy, and high-resolution transmission electron microscopy techniques. The electrochemical performances were studied by cyclic voltammetry and galvanostatic cycling in the voltage range of 2.0 to 4.0 Vat room temperature (25 °C). The compound prepared by the polymer precursor method was found to have a good cycling stability. A reversible capacity value of 203 mAh/g (2.18 mol of Li) and 170 mAh/g (1.83 mol of Li) was obtained at the end of the 70th cycle, at a current density of 30 and 120 mA/g, respectively. © Springer-Verlag 2010.
