Solid electrolytic capacitor containing a multi-layered adhesion coating

摘要

A solid electrolytic capacitor that contains an anode body, dielectric located over and/or within the anode body, an adhesion coating overlying the dielectric, and a solid electrolyte overlying the dielectric and adhesion coating that contains a conductive polymer. The adhesion coating is multi-layered and employs a resinous layer in combination with a discontinuous layer containing a plurality of discrete nanoprojections of a manganese oxide (e.g., manganese dioxide).
