Development of high-performance supercapacitor electrodes using novel ordered mesoporous tungsten oxide materials with high electrical conductivity

Abstract

An ordered mesoporous WO(3-x) material was employed for use as a supercapacitor electrode. This material exhibited a high rate capability and an excellent capacitance (366 μF cm(-2), 639 F cm(-3)), which were probably attributed to the large ordered mesopores, high electrical conductivity, and high material density.
