Ionic Liquids Containing 1,1-Dicyano-1-acetylmethanide Anion as Potential Electrolytes

Abstract

− anion, the specific capacitance of ILs bearing [DCNAcC] − anion are higher than that of IL containing [Tf 2 N] − anion and showed high temperature dependence. Such favorable electrochemical properties of these ILs are likely to be attributed to the efficient dissociation of cation and anion at higher temperature and enhanced electrosorption of [DCNAcC] − anion at the electrode.
