摘要：

An ordered mesoporous WO3-x material was employed for use as a supercapacitor electrode. This material exhibited a high rate capability and an excellent capacitance (366 mu F cm(-2), 639 F cm(-3)), which were probably attributed to the large ordered mesopores, high electrical conductivity, and high material density.
