摘要：

An asymmetric micrometer-sized pseudosupercapacitor is fabricated by growing V2O5 honeycomb nanostructures onto micro-carbon fibers, which serve as the positive electrode. WO3/PPy core/shell nanoarrays on micro-carbon fibers serve as the negative electrode. The all-solid-state pseudosupercapacitor shows a volumetric specific capacitance as high as approximate to 56 F cm(-3) and a volumetric energy density of approximate to 31.1 mWh cm(-3) while maintaining a high power density.
