Abstract
A conductive polymer capacitor includes an anode formed from a porous metal body having an anode lead extending therefrom. A dielectric layer is formed by oxidizing a surface of the anode. A solid electrolyte is formed on the dielectric layer and includes first and second polymer layers. The second conductive polymer layer includes a polyaniline layer formed by dipping the metal body having the first conductive layer thereon into a solution of doped polyaniline dissolved in an organic solvent.
