Modification of Al current collector surface by sol–gel deposit for carbon�…
Abstract Four square centimeter carbon–carbon supercapacitor cells were assembled with Al current collectors in organic electrolyte. Different treatments of the Al current collectors were made in order to increase the supercapacitor performances. A sol–gel deposit of a conducting carbonaceous material led to the best results. On the basis of electrochemical impedance spectroscopy measureme…

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…

High power density electrodes for Carbon supercapacitor applications
Abstract This paper presents results obtained with 4 cm2 Carbon/Carbon supercapacitors cells in organic electrolyte. In the first approach, a surface treatment for Al current collector foil via the sol–gel route has been used in order to decrease the Al/active material interface resistance. Performances obtained with this original process are: a low equivalent series resistance (ESR) of 0.5…

Electrode surface treatment and electrochemical impedance spectroscopy study …
ABSTRACT Power improvement in supercapacitors is mainly related to lowering the internal impedance. The real part of the impedance at a given frequency is called ESR (equivalent series resistance). Several contributions are included in the ESR: the electrolyte resistance (including the separator), the active material resistance (with both ionic and electronic parts) and the active material/c…
