On Electrical Conductivity Measurement for Lithium-Vanadium Bronze

详细

Lithium-vanadium bronze Li_1+xV₃O₈ was produced by the solid-phase method and its electrical conductivity was measured with silver and platinum electrodes. X-ray diffraction and thermal analyses demonstrated that Li_1+xV₃O₈ interacts at a temperature of 480°C with metallic silver to give AgV₂O₅ and AgV₃O₈, which is responsible for the poor reproducibility of results in electrical conductivity measurements with silver electrodes.
