ELECTROLYTIC CAPACITOR AND A METHOD OF MANUFACTURING THE SAME

摘要

In an electrolytic capacitor having a positive and a negative electrode separated by a dielectric layer, the negative electrode is electrically connected to the current collector thereof via a contact conductor, the contact conductor (contact electrode) being a film formed from a mixture of carbon black, graphite and polymerized thermosetting resin. The contact electrode is manufactured by preparing a suspension comprising carbon black, graphite, thermosetting resin and a solvent for said resin, followed by applying the resulting suspension onto the negative electrode surface and carrying out suspension coat drying at a temperature that provides for resin polymerization and solvent removal.
