Abstract

La présente invention concerne un condensateur électrolytique humide (10) qui contient une cathode, un électrolyte de travail fluide et une anode plane (200) formée à partir d'une pastille poreuse frittée ayant subi une oxydation anodique. La pastille peut être formée à partir d'une poudre de métal valve comprimée, qui à son tour, est formée par réaction d'un oxyde d'un composé de métal valve (par exemple, le pentoxyde de tantale) avec un agent de réduction qui contient un métal ayant un état d'oxydation de 2 ou plus (par exemple, le magnésium). Par l'utilisation d'une telle poudre, les présents inventeurs ont découvert que des niveaux de capacité plus élevés pouvaient être atteints par rapport à ce qui était préalablement possible pour les condensateurs haute tension utilisés dans les dispositifs médicaux implantables.
