Abstract
A polymer-based electrolyte composition having excellent film-forming properties, flexibility, mechanical strength and high hydroxide conductivity is disclosed. The composition comprises an organic polymer having an alkyl quaternary ammonium salt structure; a nitrogen-containing, heterocyclic quaternary ammonium salt; and a metal hydroxide salt. In a preferred embodiment, the composition is cast in the form of a film that is suitable for use as an ion-conducting or other specialty membrane in a power source, such as for example an alkaline battery or fuel cell, that relies on hydroxide anion transport for its operation.
