中文摘要	The ruthenium oxide has been formed by a sol-gel process. The active electrode materials was obtained by mixing aqueous solution of RuCl(3)(.)xH(2)O and NaHCO3. The crystalline structure and the electrochemical properties of the powder have been studied as a function of the annealing temperature. At lower annealing temperatures, the powder is in an amorphous phase with a lower active surface area and poor electrochemical capacitance. The fine hydrous ruthenium oxide powder with satisfactory electrochemical characteristic was obtained by annealing the powder at 210 degrees C. The active surface area of the material is improved and the capacitance is calculated to be 540 F(.)g(-1). The composite with the carbon nanotubes as support was prepared. The capacitance of composite with 20wt% CNTs is calculated to be 860 F(.)g(-1). It is also found that the addition of carbon nanotubes in ruthenium oxide could improve the power characteristics of supercapacitors.
