Solid capacitor with electrolyte containing organic material and method for producing same

Abstract

Abstract A capacitor and method for preparing the same, which includes a solid electrolyte containing a 7,7,8,8-tetracyanoquinodimethane complex and a polymer which does not dissolve the 7,7,8,8tetracyanoquinodimethane complex but disperses the same. The capacitor comprises an oxide coated anode electrode, a cathode electrode spaced from the oxide coated anode electrode and a solid electrolyte containing the 7,7,8,8-tetracyanoquinodimethane complex, and the polymer up to 40 percent by weight of the solid electrolyte and having the 7,7,8,8-tetracyanoquinodimethane complex dispersed therein. The method comprises the steps of preparing an electrode having a dielectric oxide film on its surface and a second electrode, pulverizing a 7,7,8,8tetracyanoquinodimethane complex into fine particles having particle size of 0.1 to 1 Mu m, mixing the fine particles of the 7,7,8,8-tetracyanoquinodimethane complex and a solvent for the polymer for dispersing the fine particles of the tetracyanoquinodimethane complex into a solution by a suitable method, coating the oxide film with the dispersed solution, evaporating the solvent for forming a solid electrolyte layer on the film, and contacting the second electrode to the solid electrolyte layer.
