Novel organic electrolytes comprising tetrafluoroborates and hexafluorophosphates of doubly charged cations of N,N-dialkyl-1,4- diazabicyclo[2.2.2]octanediium (DADACO) are disclosed, which have general formula (2), where R is the alkyl C1-C4, and Y- is a BF4- or PF6- anion. The invention also comprises a process for the preparation of said electrolytes comprising at least one compound of formula (2) and the use of compounds of formula (2) dissolved in an aprotic polar solvent or a mixture of such solvents as an electrolyte for an electrochemical double layer capacitor.
L'invention concerne des nouveaux électrolytes organiques comprenant des tétrafluoroborates et hexafluorophosphates de cations doublement chargés de N,N-dialkyl-1,4-diazabicyclo[2.2.2]octanediium (DADACO), et correspondant à la formule générale (2) dans laquelle R représente alkyle C¿1?-C¿4?, et Y?-¿ représente un anion BF?-¿¿4? ou PF?-¿¿6?. L'invention concerne également un procédé de préparation de ces électrolytes, lesquels comprennent au moins un composé de la formule (2), ainsi que l'utilisation des composés de la formule (2), dissous dans un solvant polaire aprotique, ou un mélange de tels solvants, en tant qu'électrolyte destiné à un condensateur double couche électrochimique.
