Abstract:
A method includes connecting together one or more anode connection members (206) of one or more anode foils (202) and one or more cathode connection members (306, 306b) of one or more cathode foils (302, 302b) and electrically isolating the one or more anode foils from the one or more cathode foils. A capacitor stack (102, 402, 402b) includes a plurality of cathode layers (302, 302b) having cathode connection members and a plurality of anode layers (202) having anode connection members (206). The anode connection members are connected to the cathode connection members and configured such that the anode layers can be electrically separated from the cathode layers by cutting only the anode connection members or the cathode connection members.
Abstract:
Composite electrodes (300) are constructed with pressure-bonding techniques instead of an adhesive. A current collector (302) is made from aluminum foil roughed on both surfaces. The surfaces of the collector can be treated to enhance adhesion to the surfaces. Layers of film (306, 307) that includes active electrode material, such as activated carbon, are fabricated and pressure-bonded to the current collector using a calendar with heated rollers. The resulting composite sheet is then processed to shape electrodes, which can be used in electrical energy storage devices, including double layer capacitors.
Abstract:
Die Erfindung betrifft ein elektrisches Bauelement (3), mit einem elektrischen Anschluß (1, 1a, 1b) , der an der Oberfläche Aluminium enthält, bei dem die aluminiumhaltige Oberfläche in einem Kontaktbereich (2) lötbar gemacht worden ist. Das Bauelement hat den Vorteil, daß durch das Löten keine plane Kontaktflächen mehr benötigt werden und zudem der ohmsche Widerstand des Kontaktes verringert werden kann.

Abstract:
An implantable medical device such as a defibrillator is described. The device includes an hermetically sealed housing containing a flat electrolytic capacitor and an energy source such as a battery. The battery is connected to the capacitor and provides charges thereto. The capacitor stores the charge at a relatively high voltage. The charge stored in the capacitor is discharged through a defibrillation lead to a site on or in the heart when fibrillation of the heart is detected by the implantable medical device. Methods of making and using the implantable medical device, the capacitor, and their various components are disclosed.
Abstract:
A capacitor (110), comprises at least two conducting elements (112, 114) for connection (116a, 116b, 118a, 118b) to an external circuit, said elements being separated by dielectric means and at least one element (112, 114) having a plurality of electrical connectors (120, 122) through which current will flow. Current and voltage fluctuations are minimised by ensuring that incoming and outgoing current flows to/from each said at least one element (112, 114) remain substantially separated.
