Abstract:
1. A method for treating capacitor material comprising: contacting single-walled carbon nanotube-containing capacitor material with a non-aqueous organic electrolyte; exposing the single-walled carbon nanotube-containing capacitor material to a first electrical potential cycling between about +1.0 V and about −1.0 V; and then exposing the single-walled carbon nanotube-containing capacitor material to a second electrical potential cycling between a positive potential greater than about +1.25 V and a negative potential less than about −1.25 V, wherein the total time of exposure is for a time sufficient to produce an activated capacitor material, and activated capacitor material refers to capacitor material after exposure to the second electrical potential cycling exhibiting an at least two-fold increase in capacitance over the capacitance of the capacitor material after exposure to the first electrical potential cycling.
