  • Method of making a multi-electrode double layer capacitor having hermetic electrolyte seal
    Publication number: 20070015336
    Abstract: A long life double layer capacitor and method of making the same including a case and a first terminal with an electrically insulating hermitic seal interposed between the first terminal and the case. A first current collector foil is electrically coupled to an interior portion of the first terminal and a first electrode comprising carbon which is juxtaposed against the first current collector foil. A porous separator is then juxtaposed against the first electrode comprising carbon and separating the first electrode from a second electrode comprising carbon. A second current collector foil is juxtaposed against a side of the second electrode and is electrically coupled to the second terminal.

  • Electrochemical double layer capacitor having carbon powder electrodes
    Patent number: 6631074
    Abstract: A method of making an electrode structure, and a double layer capacitor including the electrode structure, the method includes the steps of: applying a first slurry including conducting carbon powder and a binder to a current collector plate; curing the applied first slurry to form a primary coating; applying a second slurry that includes activated carbon powder, a solvent and a binder to the primary coating; and curing the applied second slurry to form a secondary coating, thereby forming a first electrode. In variations, additional primary and secondary coatings may be formed on both sides of the collector plate.
