  • 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
    Date of Patent: May 6, 2003
    Assignee: General Electric Company
    Inventors: Chang Wei, Elihu Calvin Jerabek, Katherine Dana DeJager, Oliver Harris LeBlanc, Jr.
  • Sealed ultracapacitor
    Patent number: 6413283
    Abstract: A multilayer cell is provided that comprises two solid, nonporous current collectors, two porous electrodes separating the current collectors, a porous separator between the electrodes and an electrolyte occupying pores in the electrodes and separator. A thermoplastic vinyl acetate polymer or thermoplastic polyamide is applied to the multilayer structure; and pressure or heat is applied to seal layers of the cell by means of the thermoplastic vinyl acetate polymer or thermoplastic polyamide to form the ultracapacitor.
    Type: Grant
