摘要:
Deposition of a metal-containing reagent solution or suspension onto a conductive substrate by various pad-printing techniques is described. This results in a pseudocapacitive oxide coating, nitride coating, carbon nitride coating, or carbide coating having an acceptable surface area for incorporation into an electrolytic capacitor, such as one having a tantalum anode.
摘要:
Deposition of a metal-containing reagent solution or suspension or a carbon nanotube-containing suspension onto a conductive substrate by various pad-printing techniques is described. In the case of a metal-containing solution or suspension, a pseudocapacitive oxide coating, nitride coating, carbon nitride coating, carbide coating, or carbon nanotube coating results. In any event, the active coating has acceptable surface area for incorporation into an electrolytic capacitor, such as one having a tantalum anode.

摘要:
An anode for an electrolytic capacitor is described. The anode is of a valve metal in powdered form, for example tantalum powder, that has been pressed into a pellet and sintered under a vacuum at high temperatures. Preferably, a poly(alkylene)carbonate binder is used to promote cohesion with the pressed powder body. The binder adds green strength to the pressed body and helps with powder flow before pressing. The poly(alkylene)carbonate binders are superior in that they leave virtually no residual carbon behind when burnt out during the sintering process. The pressed valve metal powder structure is then anodized to a desired voltage in a formation electrolyte to form a continuous dielectric oxide film on the sintered body as well as a terminal lead/anode lead weld extending therefrom.

Deposition of an electrode active material printing suspension onto a conductive substrate by various pad-printing techniques is described. After heat-treating to evaporate the solvent and decompose a printing binder, an electrode active coating suitable for incorporation into an electrochemical cell is provided.

摘要:
Terminal pins comprising a core of a first electrically conductive material selectively coated with a layer of a second electrically conductive material for incorporated into feedthrough filter capacitor assemblies are described. The feedthrough filter capacitor assemblies are particularly useful for incorporation into implantable medical devices such as cardiac pacemakers, cardioverter defibrillators, and the like, to decouple and shield internal electronic components of the medical device from undesirable electromagnetic interference (EMI) signals.
摘要:
Terminal pins that include a refractory metal forming a full perimeter weld connected to a terminal block including a dissimilar metal incorporated into feedthrough filter capacitor assemblies are discussed. The feedthrough filter capacitor assemblies are particularly useful for incorporation into implantable medical devices such as cardiac pacemakers, cardioverter defibrillators, and the like, to decouple and shield internal electronic components of the medical device from undesirable electromagnetic interference (EMI) signals.
