  • Electrodes for electrolytic capacitors and production process thereof
    Patent number: 6667247
    Abstract: This invention refers to a process for the production of an electrode for electrolytic capacitors made of a conductive substrate (7) onto which a porous layer of aluminum oxide is deposited on both sides in at least two-phase process by vacuum deposition of unstoichiometric aluminum oxide in a reactive atmosphere and a following surface oxidation process by a treatment under reactive plasma as well as a roll-to-roll system for such production and an electrode made by such process.
    Type: Grant
    Filed: September 28, 2001
    Date of Patent: December 23, 2003
    Assignee: Becromal S.p.A.
