  • Edge formation process for aluminum solid electrolytic capacitor
    Patent number: 6707663
    Abstract: A solid electrolytic capacitor comprising a foil coated with a dielectric oxide film, wherein the coated foil has slit or cut edges, and the slit or cut edges have been reformed by anodizing the foil in an aqueous oxalic acid electrolyte, then forming the foil in an aqueous citrate electrolyte, then depolarizing the foil, and then forming the foil in an aqueous phosphate electrolyte.
    Type: Grant
    Filed: March 6, 2003
    Date of Patent: March 16, 2004
    Assignee: Kemet Electronics Corporation
    Inventors: Daniel Francis Persico, Philip Michael Lessner, Albert Kennedy Harrington, Lisa Ann Sayetta

  • Edge formation process with anodizing for aluminum solid electrolytic capacitor
    Patent number: 6562652
    Abstract: Edges of a slit and cut to length foil having a dielectric oxide film on at least one surface are edge formed by comprising anodizing the foil in an aqueous oxalic acid electrolyte, further edge a forming the foil in an aqueous citrate electrolyte, preferably dibasic ammonium citrate electrolyte, depolarizing the foil, and then edge forming the foil in an aqueous phosphate electrolyte, preferably an ammonium dihydrogen phosphate.
