Abstract
This invention relates in general to components of electrochemical devices, and to methods of preparing the components. The components and methods include the use of a composition comprising an ionically conductive polymer and at least one solvent, where the polymer and the solvent are selected based on the thermodynamics of the combination. In one embodiment, the invention relates to a component for an electrochemical device which is prepared from a composition comprising a true solution of an ionically conductive polymer and at least one solvent, the polymer and the at least one solvent being selected such that |δ solvent−δ solute|<1, where δ solvent is the Hildebrand solubility parameter of the at least one solvent and where δ solute is the Hildebrand solubility parameter of the polymer. In another embodiment, the invention relates to a method of improving at least one property of a component for an electrochemical device or at least one property of the electrochemical device, the method comprising preparing the component from a composition comprising a true solution of an ionically conductive polymer and at least one solvent, the polymer and the at least one solvent being selected such that |δ solvent−δ solute|<1, where δ solvent is the Hildebrand solubility parameter of the at least one solvent and where δ solute is the Hildebrand solubility parameter of the polymer.
