Ionic liquid coated single-walled carbon nanotube buckypaper as supercapacitor electrode

---

Abstract.
Effect of stacking structure of single-walled carbon nanotubes (SWCNTs) on its performance as electrode
of supercapacitor was investigated in the present work. Considering SWCNTs easily formed bundles due
to strong van de Waals attraction between tubes, we proposed first dispersion of SWCNTs by ionic liquids
(ILs) of 1-ethyl-3-methyl imidazolium tetrafluoroborate (EMIMBF4), followed by fabrication of buckypaper
by compression. The debundling effect of ILs on SWCNTs increased the interface between electrode
and electrolyte, decreased electrical resistance, and, consequently, increased performance of the supercapacitor. Since ILs, used to disperse SWCNTs, also functioned as electrolyte in supercapacitor, our method is a simple way to prepare buckypaper electrode with high performance.
