The growth mechanism and supercapacitor study of anodically deposited amorpho…

Abstract Amorphous RuO2·xH2O and a VGCF/RuO2·xH2O nanocomposite (VGCF = vapour-grown carbon fibre) are prepared by thermal decomposition. The morphology of the materials is investigated by means of scanning electron microscopy. The electrochemical characteristics of the materials, such as specific capacitance and rate capability, are investigated by cyclic voltammetry over a voltage range of…
