Abstract
A process for preparing a solid state electrolyte used in an electrochemical capacitor includes the steps of: (a) preparing a mixture of a water-retaining clay-based mineral component and a film-forming hydroxyl-containing polymer component; (b) subjecting the mixture to a crosslinking reaction so as to form a polymer matrix membrane including a polymer matrix and an ion-permeable film; and (c) treating the polymer matrix membrane with an aqueous solution which includes a plurality of positive and negative ions so as to permit the positive and negative ions to permeate the ion-permeable film to be retained in the polymer matrix, thereby forming the solid state electrolyte.
