| Abstract: | The Ti/Ru0.1 Ti0.1 Sn0.8 O2 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 Ti/Ru0.1 Ti0.1 Sn0.8 O2 belongs to small rutile phase.A high specific capacitance of 933 F/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 electrod... |
