摘要：A thin film RuO2 electrode was prepared by spin coating thermal decomposition methods. Precursor containing RuCl3·nH2O and isopropyl alcohol was coated on tantalum substrate and annealed at 250–260°C for 3?h to form a thin film RuO2 electrode of about 2.5?μm, 5.6?μm, 11.4?μm, and 14.5?μm in thickness. X-ray diffraction revealed that peak intensities of those electrodes were similar and close to each other. Scanning electron microscopy showed that thin film of 5.6?μm in thickness was dense and free of cracks. Electrochemical performances of electrodes were examined by cyclic voltammetry, galvanostatic charge/discharge as well as equivalent series resistance. The highest specific capacitance value of 725?F?g?1 was registered for the electrode of 5.6?μm in thickness with good constant current charge/discharge and equivalent series resistance of 0.36?Ω as well as cyclic stability. ? 2017, The Minerals, Metals & Materials Society.
