Poorly crystalline Ru0.4Sn0.6O2 solid solution with size about 2 nm coated on Ti substrate was prepared by thermal decomposition at 260°C. The electrodes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) for structural and morphological studies. The Capacitance properties of the electrodes were tested by cyclic voltammetry and charge-discharge tests. The results show that the electrodes have mud-cracks structure with cracks 0.2 μm in width. The electrode has stable electrochemical capacitor properties with a maximum specific capacitance of 648 F/g within a scan potential window –0.1 - 1.0 V in 0.5 M H2SO4 electrolyte solution.
