Abstract
An organic semiconductor electrolyte capacitor and a process for producing such a capacitor having improved loss and impedance characteristics and which can be produced using a simple apparatus and with reduced waste of expensive materials. A dielectric oxide film is formed on the surface of a metal anode, and a solid-electrolyte layer is formed on the dielectric oxide film. The electrolyte layer is made by melting and solidifying a mixture of an isopropylisoquinolinium tetracyanoquinodimethane complex salt and a lactone compound.
Claims2
A process for producing an organic semiconductor electrolyte capacitor comprising:
- (1) forming a metal anode and a collector electrode;
- (2) positioning a separator between said anode and collector electrode;
- (3) forming a dielectric oxide film on a surface of said metal anode to thereby form a capacitor element, and
- (4) forming an organic semiconductor electrolyte layer on said oxide film, said organic semiconductor electrolyte layer being formed by:
- (a) mixing a lactone compound with an isopropyl-isoquinolinium tetracyanoquinodimethane complex salt,
- (b) melting said mixture by heating to a temperature lower than the melting point or thermal decomposition point of the isopropyl-isoquinolinium tetracyanoquinodimethane complex salt
- (c) dipping said capacitor element in the molten mixture,
- (d) recovering said element from the melt, and
- (e) cooling said element so as to solidify a film of said molten mixture.
