Abstract

L'invention est relative à des électrolytes pour condensateurs électrolytiques. L'électrolyte comprend un sel d'un acide aliphatique dicarboxylique non saturé ayant deux atomes centraux de carbone éthylène entre les groupes carboxyles, et une base contenant de l'azote. Le sel est dissous dans de l'éthylène glycol avec une concentration molaire inférieure à 0,3. Application aux condensateurs électrolytiques à anode en aluminium.The invention relates to electrolytes for electrolytic capacitors. The electrolyte comprises a salt of an unsaturated aliphatic dicarboxylic acid having two central ethylene carbon atoms between the carboxyl groups, and a nitrogen-containing base. The salt is dissolved in ethylene glycol with a molar concentration of less than 0.3. Application to electrolytic capacitors with aluminum anode.
