Ionic semiconductor materials and applications thereof

Abstract

An electrode comprising: metallic electrode material; and a nonporous solid composite material encapsulating the electrode material, the composite material comprising an inert matrix material having hydrogel substantially uniformly dispersed therein, the hydrogel comprising 10% to approximately 50% by weight of the dry composite material, there being sufficient bonding between molecules of the hydrogel and the matrix material to prevent substantial leach-out of hydrogel molecules from the composite.
