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 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 present inventors have discovered a technique that is believed to substantially improve the uniformity and consistency of the manganese oxide layer.

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.

摘要： A pressed anode formed from an electrically conductive powder that contains a plurality of coarse agglomerates and fine agglomerates is provided. The fine agglomerates have an average size smaller than that of the coarse agglomerates so that the resulting powder contains two or more distinct particle sizes, i.e., a “bimodal” distribution. In this manner, the fine agglomerates can effectively occupy the pores defined between adjacent coarse agglomerates (“inter-agglomerate pores”). Through the occupation of the empty pores, the fine agglomerates can increase the apparent density of the resulting powder, which improves volumetric efficiency.
摘要翻译：提供由含有多个粗团块和细小附聚物的导电粉末形成的压制阳极。细小的附聚物的平均尺寸比粗团块的平均尺寸小，因此得到的粉末含有两种或更多种不同的粒度，即“双峰”分布。以这种方式，细小的附聚物可以有效地占据相邻粗糙附聚物（“团聚孔”）之间限定的孔。通过占用空孔，细小的团块可以增加所得粉末的表观密度，从而提高体积效率。
