  • Electrochemical double layer capacitor having carbon powder electrodes
    Patent number: 6955694
    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.
    Type: Grant
    Filed: January 30, 2003
    Date of Patent: October 18, 2005

  • Electrochemical double layer capacitor having carbon powder electrodes
    Patent number: 6946007
    Abstract: A method of making an electrode structure, the electrode structure and a double layer capacitor including the electrode structure, the method comprising the steps of: forming a plurality of electrodes, each having a current collector plate, a primary coating formed on each side of the collector plate, the primary coating including conducting carbon powder and a binder, and a secondary coating formed on each primary coating, the secondary coating including activated carbon powder, a solvent and a binder; positioning a respective separator between each electrodes while stacking the electrodes such that the respective separator is juxtaposed against respective secondary coatings of adjacent electrodes that electrically insulates the adjacent electrodes, whereby forming an electrode stack; and rolling the electrode stack into a cylindrical electrode structure.
