Abstract
A solid electrolytic capacitor is disclosed. The capacitor comprises an organophosphorus material positioned between the dielectric layer and the polymeric electrolyte layer. The organophosphorus compound improves the interlayer adhesion between the dielectric and electrolyte layers.
Claims12
A solid electrolytic capacitor comprising:
- (a) an anode,
- (b) a dielectric material covering the surface of the anode,
- (c) a layer of an organophosphorus material at least partially covering the dielectric layer, wherein the organo group of the organophosphorus material is a π conjugated oligomer or polymer, and
- (d) a layer of a conductive polymer at least partially covering layer (c).
