Title
(EN) CAPACITOR WITH DUAL ELECTRIC LAYER
(FR) CONDENSATEUR A COUCHE ELECTRIQUE DOUBLE
Abstract
(EN) The present invention relates to a capacitor with a dual electric layer, wherein said capacitor includes a pair of electrodes, one or both of which can be polarised, as well as a liquid electrolyte and a separator. This capacitor is characterised in that the porous space of the separator and both electrodes is filled with the electrolyte up to a level representing from 90 to 40 % of the pore total volume.
(FR) Cette invention concerne un condensateur à couche électrique double qui comprend deux électrodes, dont l'une ou les deux peuvent être polarisées. Ce condensateur comprend également un électrolyte liquide et un séparateur. Ce condensateur se caractérise en ce que le niveau de remplissage en électrolyte de l'espace poreux du séparateur et des deux électrodes représente de 90 à 40 % du volume total des pores.
