ABSTRACT:
Materials possessing ionic conductivity which are suitable for use as electrolytes, notably in electrochromic systems, comprising an ionomer obtained by the neutralization of a Bronsted polyacid by an MOH alkali metal hydroxide, the neutralization rate .alpha. being such that 0<.alpha.<.alpha..sub.m, where .alpha..sub.m is the neutralization rate beyond which a phase separation takes place. The ionomer comprises a polymeric chain having a plurality of anionic groups affixed thereto and a plurality of alkaline cations associated therewith. The material further comprises a polar solvent, capable of solubilizing or plasticizing the ionomer and of assuring a partial ionic diassociation as well as transporting the M.sup.+ ions. Optionally, this material may comprise, in addition to the above, a Bronsted polybase soluble in the polar solvent which does not form a solid precipitate with the ionomer and an MX inorganic salt wherein M.sup.+ is the same alkaline cation as that utilized to neutralize the polyacid and X is a monovalent anion.
