Abstract: A capacitor assembly that is capable of exhibiting good electrical properties even under a variety of conditions is provided. More particularly, the capacitor contains a capacitor element that includes a sintered porous anode body, a dielectric that overlies the anode body, and a solid electrolyte that overlies the dielectric. The solid electrolyte contains an adhesion layer that is positioned between an inner conductive polymer layer and an outer conductive polymer layer. The adhesion layer is formed from an organometallic compound and the outer layer is formed from pre-polymerized conductive polymer particles.
