摘要:
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 hydro-carbon 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 10−5 S/cm at room temperature (24° C.).

摘要:
Solid proton conductors are described, which are based on zeolites having oton-containing cations and having six-member and larger rings as secondary structural groups of the zeolitic structure, and in whose crystal lattice passages a phase is present which promotes proton transport. Their use as separator material and electrolyte for electrochemical cells is also described.
