Abstract: A method for producing an amorphous activated carbon material includes heating a carbon precursor to a temperature effective to form a partially-dense amorphous carbon, and activating the partially-dense amorphous carbon to produce an amorphous activated carbon. To facilitate efficient activation of the amorphous carbon, the carbonization is controlled to produce an amorphous carbon material that, prior to activation, has a density of from 85% to 99% of a maximum density for the amorphous carbon.

Abstract: Nanoporous activated carbon material having a high specific capacitance in EDLCs and controlled oxygen content, and methods for making such activated carbon material. Reduction of oxygen content is achieved by (a) curing a carbon precursor/additive mixture in an inert or reducing environment, and/or (b) refining (heating) activated carbon material after synthesis in an inert or reducing environment. The inert or reducing environment used for curing or refining is preferably substantially free of oxygen.
