The present invention is concerned with novel polar solvents and novel electrolytic compositions comprising such solvents, and having a high range of stability, as required for applications in the field of electrochemistry. The present solvents have a highly polar amide function, and preferably combine with a salt soluble in the solvent and having an anion with a delocalized charge, and at least one polymer, to form an electrolytic composition.

Solvents and novel electrolytic compositions having a large range of stability and high conductivity

The copolymer described is a segmented copolymer consisting essentially of organic segments A which have a number i of reactive ends such that i is from 1 to 6 inclusive, and segments B which have a number j of reactive ends such that j is from 1 to 6 inclusive. The segments B have redox properties and each segment A is connected to at least one segment B by a group Y and vice versa, the group Y being an ether, thioether, secondary amine, tertiary amine, secondary amide, tertiary amide, imide, quarternary ammonium group, or a group having a carbon--carbon bond. The respective weighted molar mean of i and j is 2 or more. Application to electrochemical generators and electrochromic systems.
