Abstract: A method includes dispensing ion-conducting particles on a substrate comprising an adhesive to which the ion-conducting particles adhere; overcoating the ion conducting particles with a polymer; removing the substrate and the adhesive from the ion conducting particles; and removing a polymer overburden on the ion conducting particles to form a device that includes: (i) the polymer or a derivative thereof, and (ii) ion-conducting particles. At least a portion of the ion-conducting particles extend through the polymer or its derivative.

Abstract: A device includes a membrane that is: (i) impermeable to oxygen, and (ii) insoluble in at least one polar solvent; and ion conducting particles in the membrane. At least some of the particles extend from a first side of the membrane to an opposed second side of the membrane. The thickness of the membrane is 15 ?m to 100 ?m.
