A double-layer capacitor includes a first electrode having a first polarity, a second electrode having a second polarity, the first polarity being different from the second polarity, and an electrolyte that is in contact with the first electrode and the second electrode. The first electrode has a first charge of the first polarity and the second electrode has a second charge of the second polarity, and maximum values of the first charge and the second charge are substantially equal.

Double-layer capacitor, use of the same, and method for increasing the maximum charges of double-layer capacitor electrodes

An electrode includes a collector that is substantially flat and electrically conductive, an inner intermediate layer that is substantially corrosion resistant and conductive and that is on at least part of a surface of the collector, and an outer intermediate layer that is substantially corrosion resistant and conductive and that is on at least part of the inner intermediate layer. The electrode also includes an electrode layer containing carbon, which is on at least part of a surface of the outer intermediate layer that faces away from the inner intermediate layer.

Electrode and method for the production thereof

An electrode includes a current collector that is two-dimensional in shape and that contains perforations, and an intermediate layer that is electrically conductive and substantially corrosion-resistant. The intermediate layer is on at least part of a first surface of the current collector, and includes at least one of precious metal, graphitic carbon, a metal nitride, and a metal carbide. A first electrode layer is on the intermediate layer. At least part of the first electrode layer is in at least some perforations of the current collector. The first electrode layer, the intermediate layer, and the current collector are bonded together.

Capacitor electrodes

A method to produce a layer electrode for electrochemical components with a layer applied to a metal film to produce a connection between the metal film and the layer by softening the metal film and pressing a surface section of the layer over a part of the thickness of the layer into the softened metal film. The ohmic resistance of the layer electrode can be reduced in an advantageous manner via the pressing of surface sections of the layer into the metal film.
