Abstract
A method for producing activated carbon includes heating a phenolic novolac resin carbon precursor at a carbonization temperature effective to form a carbon material, and reacting the carbon material with CO2 at an activation temperature effective to form the activated carbon. The resulting activated carbon can be incorporated into a carbon-based electrode of an EDLC. Such EDLC can exhibit a potential window and thus an attendant operating voltage of greater than 3V.
