| 英文摘要 | Wo3 microspheres film with a tertiary, textured and porous structure assembled of wo3 hierarchical nanorods has been directly prepared on cu foil using a one-step hydrothermal method. the field emission scanning electron microscopy (fesem), energy dispersive x-ray (edx) spectrum, x-ray diffraction (xrd), high resolution transmission electron microscopy (hrtem), x-ray photoelectron spectroscopy (xps) are used to reveal the surface microtopography, crystal structure, elementary composition, valence state and formation mechanism of wo3 tertiary structure. moreover, the electro-chemical properties and supercapacitive performances of wo3 microspheres film are also intensively investigated. the wo3 microspheres film has high specific capacitances of 485, 426, 372, 319 and 260 f g(-1) at unit currents of 0.5, 1, 2, 5 and 10 a g(-1) and exhibits good cycle stability (93% after 5000 cycles) and reversibility (98.5%), a lower charge transfer resistance (0.5 omega) and high energy densities ranging from 21 to 17 w h kg(-1) corresponded to high power densities varied from 150 to 3000 w kg(-1).
