Applying the melt quenching method (cooling rate 101-102K/s), new multicomponent vanadate glasses were synthesized, containing different amounts of MoO3 at the expense of B2O3 with the composition 20Li2O:(30-х)B2O3:50V2O5:xMoO3, x = 10, 20 mol%. The obtained samples were characterized by X-ray diffraction, infrared spectroscopy, differential scanning calorimetry and impedance spectroscopy. The density of the glasses was measured by the Archimedes method, on the basis of which the physicochemical parameters molar volume, oxygen molar volume and oxygen packing density were calculated. It was found that the replacement of B2O3 with MoO3 leads to changes in electrical conductivity, which are a consequence of the increase in non-bridging oxygen atoms in the amorphous structure. The electrochemical characterization of the 20Li2O:(30-х)B2O3:50V2O5:20MoO3 glass obtained was performed by assembling an all-solid-state cell, employing 20Li2O:(30-х)B2O3:50V2O5:20MoO3 glass as a cathode active material. The obtained results show that the studied glass composition is interesting in view of their potential application as cathode materials in all-solid-state lithium-ion batteries.
