Festelektrolytkondensator zur Verwendung unter extremen Bedingungen

Eine Kondensatorbaugruppe, die unter extremen Bedingungen, wie hohen Temperaturen und/oder hohen Spannungen, leistungsfähig sein kann, wird bereitgestellt. Die Fähigkeit, bei hoher Temperatur leistungsfähig zu sein, wird zum Teil dadurch erreicht, dass das Kondensatorelement innerhalb eines Gehäuses in Gegenwart einer Gasatmosphäre, die ein Inertgas enthält, eingeschlossen und hermetisch versiegelt ist, wodurch die Menge an Sauerstoff und Feuchtigkeit, die dem festen Elektrolyten des Kondensatorelements zugeführt wird, begrenzt ist. Weiterhin haben die Erfinder auch herausgefunden, dass die Fähigkeit, bei hohen Spannungen leistungsfähig zu sein, durch eine einzigartige und gezielte Kombination von Merkmalen, die sich auf die Bildung der Anode, des Dielektrikums und des festen Elektrolyten beziehen, erreicht werden kann. Zum Beispiel wird der feste Elektrolyt aus einer Kombination eines leitfähigen Polymers und eines hydroxyfunktionellen nichtionischen Polymers gebildet.
