Abstract:
A capacitor is described. The capacitor includes a casing of first and second casing members secured to each other to provide an enclosure, a feedthrough electrically insulated from the casing and extending there from through a glass-to-metal seal, first and second anodes electrically connected to each other within the casing, a cathode, and an electrolyte. The cathode is of a cathode active material deposited on planar faces of the first and second casing members. There is also a cathode current collector disposed intermediate the first and second anodes. The cathode current collector supports cathode active material on both of its major faces and includes a tab that is directly electrically connected to a ferrule of the glass-to-metal seal. That way, the casing is the negative terminal for the cathode and a feedthrough pin extending through the glass-to-metal seal is the positive terminal for the anode of the capacitor.

Abstract:
Structures for serially connecting at least two capacitors together are described. Serially connecting capacitors together provides device manufactures, such as those selling implantable medical devices, with broad flexibility in terms of both how many capacitors are incorporated in the device and what configuration the capacitor assembly will assume.
In various examples, a component is for use in an implantable medical device. The component includes a pin including a first material attached to a lead including a second material different from the first material of the pin. At least a portion of the lead includes a channel in which at least a portion of the pin sits, the channel including a channel opening defined at least partially by opposing first and second channel sides extending a channel length. At least a first joint is formed along at least a portion of the first channel side. The first joint includes the second material of the lead deformed to at least partially close the channel opening to retain the pin within the channel to attach the lead to the pin. In some examples, the first material includes molybdenum and the second material includes aluminum.
Titanium Clad Nickel Termination-Pad Welded To A Titanium Tab For A Capacitor

International Classification:
H01G 9/06 H01G 9/10 H01G 9/008
Abstract:
A nickel termination-pad that has been clad-bonded to a titanium base layer electrically contacted to a casing to thereby serve as a surface for a device manufacturer to connect electronic circuit to the capacitor is described. The clad connection of the nickel termination-pad to the titanium base layer is both robust and provides good electrical conductivity between the dissimilar metals.
Closure System For The Electrolyte Fill Port Of An Electrochemical Cell

International Classification:
H01M 2/36 H01M 2/02
Abstract:
A closure system for the electrolyte fill port of an electrochemical cell is described. A cell header has an electrolyte fill port comprising an upper opening sidewall extending from a header upper surface to an intermediate ledge located part-way through the header thickness. The ledge extends from a lower edge of the upper opening sidewall to an upper edge of a lower opening sidewall, the lower opening sidewall extending to the header lower surface. With respect to an axis of the electrolyte fill port, the upper opening sidewall has a first radius rand the lower opening sidewall has a second radius rat the ledge, the lower opening sidewall extending downwardly and inwardly along the axis from the second radius rto a third radius rat the header lower surface. The second radius rat the ledge is greater than the third radius rat the header lower surface. A closure system for an electrolyte fill port comprises a lower closure member secured to the lower opening sidewall by a lower weld; and an upper closure member secured to the upper opening sidewall by an upper weld. Importantly, the lower opening sidewall is provided with rifling.
