Abstract:
Disclosed is an electroconductive material which contains at least a vanadium oxide and a phosphorus oxide, and has a crystalline structure composed of a crystalline phase and an amorphous phase, in which the crystalline phase contains a monoclinic vanadium-containing oxide, and a volume of the crystalline phase is larger than that of the amorphous phase.The electroconductive material has a reduced specific resistance and has improved functions as an electrode material, a solid-state electrolyte, or a sensor such as a thermistor.
