Abstract: 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.

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.

Regardless, the dispersion may be more easily and cost effectively formed and incorporated into the structure of the capacitor. Moreover, due to the presence of the ionic liquid, the dispersion is conductive and does not require the addition of conventional dopants, such as polystyrene sulfonic acid.
