Capacitor with very high energy per unit volume and supervised self-healing

Abstract

Abstract The invention relates to a capacitor with very high energy per unit volume, of the type produced by coiling at least two metallised dielectric films, the metallisations including two zones of different thicknesses, a first zone 14 of small thickness so as to facilitate the self-healing phenomena and a second, lateral and thicker zone 13 constituting a reinforced edge. The metallisation of the films is also crenellated so as to form electrodes of elementary capacitors, these electrodes being joined to the reinforced edge 13 by a metal zone 15 of narrow width situated in the thick metal zone.
