LiV3O8 cathode has been synthesized by two simple low temperature methods without involving the melting of V2O5 and characterized by X-ray diffraction, scanning electron microscopy (SEM), discharge-charge measurements in lithium cells and differential scanning calorimetry (DSC). While the first method involves the heating of the components in H2 at 500 °C followed by in N2 at 600 °C, the second method involves the dispersion of the components in methanol followed by evaporating the solvent and heating at 500 °C in N2 atmosphere. The samples exhibit a high capacity of around 230 mAh g-1 at 0.5 mA cm-2 and 25 °C in a narrow voltage range of 2-3.5 V with excellent cyclability at -30 to 60 °C. Additionally, the samples exhibit superior safety characteristics compared to the currently used LiCoO2 cathode as indicated by the absence of exothermic peaks (DSC) up to 450 °C in the charged state.
