  • Method of making an ultracapacitor electrode
    Patent number: 6558437
    Abstract: A paste of organic solvent with dissolved organic salt and active carbon is formed and a uniform film of the paste is applied onto a substrate by casting the paste into a clearance between a knife blade and the substrate. The paste is evaporated to form a paste electrode for an ultracapacitor.
    Type: Grant
    Filed: August 21, 2001

  • Ultracapacitor electroyte
    Patent number: 6256190
    Abstract: The invention relates to an ultracapacitor and to a method of making an ultracapacitor. The ultracapacitor of the invention includes two solid, nonporous current collectors, two porous electrodes separating the collectors, a porous separator between the electrodes and an electrolyte occupying the pores in the electrodes and separator. The electrolyte includes a cyclic carbonate solvent, a cyclic ester solvent and an electrolyte salt. The invention also relates to a stack of ultracapacitor cells.
