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 pre-coat layer that overlies the dielectric and is formed from an organometallic compound. A solid electrolyte overlies the pre-coat layer that contains an inner layer and an outer layer, wherein the inner layer is formed from an in situ-polymerized conductive polymer and the outer layer is formed from pre-polymerized conductive polymer particles.

Abstract: A capacitor assembly that is capable of exhibiting good properties under dry conditions. The ability to perform under such conditions is due in part to the use of an intrinsically conductive polymer in the solid electrolyte that contains repeating units having the following formula (I): wherein, R is (CH2)a—O—(CH2)b; a is from 0 to 10; b is from 1 to 18; Z is an anion; and X is a cation.
