The invention relates to methods for manufacturing an energy storage of an electrolytic capacitor, to a method for manufacturing a foil electrode of an aluminum electrolytic capacitor, to a device for manipulating a component of an aluminum electrolytic capacitor, to specifically designed foil electrodes for an aluminum electrolytic capacitor, to a method and a device for analyzing a quality of a section of paper to be used as separator of an electrolytic capacitor, and to a specifically designed electrolytic capacitor.

Electrolytic capacitor components and manufacturing methods

An embodiment of the capacitor includes a metal current collector, a conductive adhesion layer applied on the metal current collector, and an electrode active layer applied on the conductive adhesion layer, wherein the adhesion layer has a conductive non-carbide metal compound, particularly a metal oxide or metal nitride. An embodiment of the method of manufacturing the capacitor is also disclosed.

Capacitor with conductive adhesion layer

The invention relates, amongst others, to a feedthrough pin of an electrolytic capacitor for contacting an electrode of the electrolytic capacitor and providing an electrical contact of the electrolytic capacitor on an outside of the electrolytic capacitor, the feed-through pin comprising a longitudinally extending body. According to an aspect of the invention, a first circumferential protrusion is arranged between a first section of the longitudinally extended body and a second section of the longitudinally extended body, wherein the first circumferential protrusion runs around a longitudinal axis of the longitudinally extended body and extends radially outwards over an outer contour of the first section of the longitudinally extended body and an outer contour of the second section of the longitudinally extended body.

Electrical feed-through of an electrolytic capacitor

The present invention relates to a capacitor having an electrically conductive housing with a housing inner surface and a housing interior substantially defined by the housing inner surface, at least one first electrode having a first polarity and being arranged in the housing interior, at least one separator element being arranged between the housing inner surface and the at least one first electrode, and an electrically conductive coating being arranged between the housing inner surface and the at least one separator element. The housing inner surface includes at least one recess, and the electrically conductive coating is arranged in the at least one recess.
