Abstract

Un condensateur (10) à électrolyte humide est proposé. Le condensateur (10) inclut une anode plane (200, 201, 202, 203, 300, 400, 500) formée à partir d'une poudre pressée et frittée, une cathode qui inclut un substrat métallique qui est revêtu avec un matériau électro-chimiquement actif et un électrolyte opérationnel en communication avec l'anode plane (200, 201, 202, 203, 300, 400, 500) et la cathode. L'anode plane (200, 201, 202, 203, 300, 400, 500) comporte une portion évidée (46, 146, 246) formée dans au moins une de ses surfaces. Le condensateur (10) inclut également au moins une retenue (48, 148, 248) qui est en contact avec la portion évidée (46, 146, 246) et présente une forme qui correspond généralement à une forme de la portion évidée (46, 146, 246). La portion évidée (46, 146, 246) de l'anode plane (200, 201, 202, 203, 300, 400, 500) permet la stabilisation de l'anode plane (200, 201, 202, 203, 300, 400, 500) par l'intermédiaire d'une retenue (48, 148, 248) sans augmenter les dimensions du condensateur (10).
