Abstract

Supercapacitor can get high energy density and the ability of quick charging and discharging. In this work, the different mass ratios of composite electrodes mixed with active carbon (AC) based on RuO2•xH2O, were prepared to study the electrical performance parameters of the incorporations. Through Conway’s model and impedance spectroscopy, the composite electrode model has been established, and it is validated by the experiments on their electrochemical performances for different proportions of composite electrodes fabricated with RuO2•xH2O and active carbon. The simulation results show that the composite electrode with 60wt.% amorphous hydrous ruthenium oxide has the lower inner resistance and the higher degree of ruthenium oxide utilization, which are testified by the experiments.
