Ti/Ru0.1Ti0.1Sn0.8O2 electrodes were prepared by low temperature thermal decomposition. The structural characteristics were analyzed by X-ray diffraction(XRD).The performances were tested by cyclic voltammetry and constant current charge-discharge measurements. The results show that, the structure of Ti/Ru0.1Ti0.1Sn0.8O2 belongs to small rutile phase. A high specific capacitance of 933F/g is obtained at scan rate of 20 mV/s. The cycle life test shows a 23.6% specific capacitance lost after 1000 cycles. The electrode has a good cycle stability and reversibility.
