An Innovative and Viable Route for the Realization of Ultra-Thin Supercapacitors Electrodes Assembled with Carbon Nanotubes

Electrochemical Double Layer Capacitors (EDLC), also known as supercapacitors, have been fabricated using Single Walled Carbon Nanotubes (SWCNTs) as active material for electrode assembling. In particular a new way of fabrication of ultra-thin electrodes (<= 25 mu m) directly formed on the separator has been proposed, and a prototype of EDLC has been realized and tested. For such devices the specific capacitance is in the range 40-45 F/g and the internal resistances in the range 6-8 Omega center dot cm(2), at current density of 2 mA center dot cm(-2).
