Materials having proton conduction (by protons or by both protons and alkaline ions), process for their preparation and their applications

摘要

The invention relates to an anhydrous macromolecular material having proton conduction, characterised in that it consists essentially of a solid solution of at least one acid salt of a strong acid derived from an alkaline cation of formula: [M<->]x[HyXO4] in which: M<+> is an alkali metal ion or the ammonium ion X is a sulphur, selenium or phosphorus atom x and y are non-zero indices consisting of whole numbers which can take values such as (x=1, y=1), (x=2, y=1) or (x=1, y=2), dissolved in a polymer - homo- and/or copolymer - having linear or crosslinked chains containing hetero atoms capable of forming complexes with the released proton species or proton species which can be released by the acid salt of a strong acid. Use of these macromolecular materials according to the invention as electrolytes, electrodes or both, in electrochemical generators.
