An electrode used for resistance welding is described. In an embodiment, the electrode comprises a two-part construction having an electrode tip portion that is removably contactable to an electrode base. The electrode is constructed such that the respective base and electrode tip portions may be composed of metals having differing melting temperatures, in particular a significant difference in melting temperature of at least 100&#xb0; C. or more. The electrode is preferably constructed so that the electrode tip portion can be easily removed, thereby leaving the base portion within the fixture.

Sacrificial resistance weld electrode

A fixture in which an attractive magnetic force is utilized to join two parts of a container or housing together is discussed. The fixture comprises a fixture body portion, a fixture base portion and a removable fixture plate portion. At least one body magnet resides within the fixture body portion and at least one plate magnet resides within the removable fixture plate. The fixture body and plate magnets are positioned such that when they are brought together, an attractive magnetic force pulls the plate towards the fixture body. Therefore, when the respective housing portions are positioned within the fixture, the magnetic force compresses the housing portions together.

Magnetic fixture

An electrode assembly constructed of continuous anode and cathode electrodes that are overlaid in overlapping fashion and wound into a cell stack suitable for prismatic and cuboidal-shaped cases. The cathode electrode strip has some regions where the electrode material is pressed to a high density and has some regions where the active material is substantially removed from the current collector screen.

Method for providing a current collector with bare regions to facilitate winding

A system and method for cutting and heat sealing polypropylene film and/or other separator material around individually shaped cathode, anode or other active components, for use in a battery or capacitor and/or other implantable medical device.
