Abstract
A method of producing an alkaline single ion conductor with high conductivity includes: a) providing a hydrocarbon oligomer or polymer having immobilized acidic substituent groups selected from the group consisting of a sulfonic acid group, sulfamide group, a phosphonic acid group, or a carboxy group, in its alkaline ion form wherein at least a part of the acidic protons of the substituent groups have been exchanged against alkali cations, and b) solvating the hydrocarbon oligomer or polymer of step a) in an aprotic polar solvent for a sufficient time to effect a solvent uptake of at least 5% by weight and to obtain a solvated product, wherein the molar ratio of solvent/alkaline cation is 1:1 to 10,000:1, and which solvated product has a conductivity of at least 10S/cm at room temperature (24° C.).
