Abstract

An electrolyte composition (A) containing at least one aprotic organic solvent and at least one compound of formula (I) wherein A+ is selected from Li+, Na+, K+, Cs+, and ammonium; is a bidentate radical derived from a (hetero)aromatic 1,2-, 1,3- or 1,4-diol, from a (hetero)aromatic 1,2-, 1,3- or 1,4-dicarboxylic acid or from a (hetero)aromatic 1,2-, 1,3- or 1,4-hydroxycarboxylic acid by abstracting the two H atoms of pairs of adjacent OH groups; and R1 and R2 are organic substituents.
