a b s t r a c t Single-walled carbon nanotubes (SWCNTs)were investigated by cyclic voltammetry and electrochemical impedance spectroscopy in a non-aqueous electrolyte, 1M Et4NBF4 in acetonitrile, suitable for supercapacitors. Further, in situ dilatometry and in situ conductance measurements were performed on single electrodes and the resultscompared to an activated carbon, YP17. Both material…
Abstract. The electrochemical doping of single-walled carbon nanotubes (SWCNTs) in 1 M Et4NBF4 in acetonitrile was investigated by in situ Raman spectroscopy. The capacitance was determined to be 82 F/g for the positive and 71 F/g for the negative SWCNT electrode, respectively, which approaches the typical values for microporous activated carbons used in supercapacitors. The changes in the…
