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.

Abstract: A carbon-based electrode includes activated carbon, carbon black, and a binder. The binder is fluoropolymer having a molecular weight of at least 500,000 and a fluorine content of 40 to 70 wt. %. A method of forming the carbon-based electrode includes providing a binder-less conductive carbon-coated current collector, pre-treating the carbon coating with a sodium napthalenide-based solution, and depositing onto the treated carbon coating a slurry containing activated carbon, carbon black and binder.

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.

Abstract: Stabilized lithium particles include a lithium-containing core and a coating of a complex lithium salt that surrounds and encapsulates the core. The coating, which is a barrier to oxygen and water, enables the particles to be handled in the open air and incorporated directly into electrochemical devices. The coating material is compatible, for example, with electrolytic materials that are used in electrochemical cells. The average coated particle size is less than 500 microns.

Abstract: A method of forming an electrolyte solution involves combining ammonium tetrafluoroborate and a quaternary ammonium halide in a liquid solvent to form a quaternary ammonium tetrafluoroborate and an ammonium halide. The ammonium halide precipitate is removed from the solvent to form an electrolyte solution. The reactants can be added step-wise to the solvent, and the method can include using a stoichiometric excess of the ammonium tetrafluoroborate to form a substantially halide ion-free electrolyte solution.
