摘要： A solid electrolytic capacitor that includes an anode body, a dielectric overlying the anode body, a solid electrolyte that contains one or more conductive polymers and overlies the dielectric, and an external coating that overlies the solid electrolyte, is provided. The external coating includes at least one carbonaceous layer (e.g., graphite) and at least one metal layer (e.g., silver). In addition to the aforementioned layers, the external coating also includes at least one conductive polymer layer that is disposed between the carbonaceous and metal layers. Among other things, such a conductive polymer layer can reduce the likelihood that the carbonaceous layer will delaminate from the solid electrolyte during use. This can increase the mechanical robustness of the part and improve its electrical performance.

摘要： A solid electrolytic capacitor that contains an anode body formed from an electrically conductive powder and a dielectric coating located over and/or within the anode body 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 a manganese precursor solution (e.g., manganese nitrate) can be readily impregnated into the pores of the anode. This is accomplished, in part, through the use of a dispersant in the precursor solution that helps minimize the likelihood that the manganese oxide precursor will form droplets upon contacting the surface of the dielectric. Instead, the precursor solution can be better dispersed so that the resulting manganese oxide has a “film-like” configuration and coats at least a portion of the anode in a substantially uniform manner. This improves the quality of the resulting oxide as well as its surface coverage, and thereby enhances the electrical performance of the capacitor.

摘要： A solid electrolytic capacitor that is capable of withstanding laser welding without a significant deterioration in its electrical performance is provided. The capacitor contains an anode body, dielectric layer overlying the anode body, and a solid organic electrolyte layer overlying the dielectric layer. Furthermore, the capacitor of the present invention also employs a light reflective layer that overlies the solid organic electrolyte layer. The present inventors have discovered that such a light reflective layer may help reflect any light that inadvertently travels toward the capacitor element during laser welding. This results in reduced contact of the solid organic electrolyte with the laser and thus minimizes defects in the electrolyte that would have otherwise been formed by carbonization. The resultant laser-welded capacitor is therefore characterized by such performance characteristics as relatively low ESR and low leakage currents.
