Abstract: A solid electrolytic capacitor that contains an anode body formed from an electrically conductive powder, dielectric located over and/or within the anode body, an adhesion coating overlying the dielectric, and a solid electrolyte overlying the adhesion coating is provided. The powder has a high specific charge and in turn a relative dense packing configuration. Despite being formed from such a powder, the present inventors have discovered that the conductive polymer can be readily impregnated into the pores of the anode. This is accomplished, in part, through the use of a discontinuous precoat layer in the adhesion coating that overlies the dielectric. The precoat layer contains a plurality of discrete nanoprojections of a manganese oxide (e.g., manganese dioxide).

Abstract: A method for manufacturing a solid electrolytic capacitor with excellent ESR properties and a solid electrolytic capacitor. A method for manufacturing a solid electrolytic capacitor, wherein an anode body is obtained by forming a dielectric oxide film on the surface of a sintered body that is formed by sintering a molded body formed of a valve acting metal powder or on the surface of a roughened valve acting metal foil, and a solid electrolyte layer is formed on the surface of the anode body. This method for manufacturing a solid electrolytic capacitor is characterized by steps for forming a solid electrolyte layer including a protrusion forming process where protrusions formed of manganese dioxide and having an average diameter of 10˜102 nm are formed on the surface of the dielectric oxide coating film so that the protrusions are scattered about like islands and the surface coverage is 1˜20% and a conductive polymer layer forming process where a conductive polymer layer is formed on the surfaces of the projections and the dielectric oxide coating film.
