Influence of carbon nanotubes addition on carbon–carbon supercapacitor perf…

Abstract This paper presents the performances of 4 cm2 supercapacitors cells assembled with 200 m thick active material films composed with activated carbon and carbon nanotubes mixture in organic electrolyte. Galvanostatic and electrochemical spectroscopy impedance measurements have been carried out. Galvanostatic measurements show that both internal resistance and specific capacitance decrea…
