Solid electrolytic capacitors comprising a conductive layer made of a polymer of pyrrole or its derivative
摘要
A solid electrolytic capacitor is composed of a pair of electrodes and a dielectric film therebetween, wherein one electrode includes a conducting polymer doped with a polyvalent anion and a monovalent anion. The conducting polymer layer may have a multi-layer structure wherein a second or third conductive polymer layer is made of doped thiophene or derivative thereof.
