Sažetak
A number of composite electrodes synthesized by casting a suspension of different amounts of ruthenium oxide (RuO2) in the solutions of poly(vinylidene fluoride) (PVDF) or Nafion® as binders onto glassy carbon (GC) electrodes and covered subsequently by various quantities of deposited polyaniline (PANI) were investigated as the electrodes for applications in electrochemical supercapacitors. The electrochemical properties of the composite electrodes were investigated by cyclic voltammetry and electrochemical impedance spectroscopy techniques. It has been shown that for the composites with lower mass of RuO2 specific capacitance of about 500 F g-1 is achieved with PVDF as a binder and PANI formed in 6 potential cycles. For the same composites, however, better power characteristics could be expected for Nafion® as the binder.
