【Abstract】 Amorphous hydrous ruthenium oxide/active carbon composite electrode materials prepared by the liquid phase codeposition. The morphology of the conductive agents were investigated by SEM. Based on the cyclic voltammetry,AC impedance spectroscopy and constant current charge-discharge techniques,the performances of the RuO2/AC composite electrodes materials which add different conductive agent are investigated. The results show that when CNTs,AB,KS6 and Super P Li were used as conductive agent,the materials specific capacitance of RuO2/AC composite electrodes was689,556,574 and 512 F/g,respectively,the equivalent series resistance was 0. 19,0. 36,0. 32 and 0. 41 Ω,measured at 5 m V/s in 38%(mass fraction) H2SO4 and under the current density of 2 m A/cm2.更多还原
