  • Patent number: 9991055
    Abstract: A capacitor assembly that is capable of exhibiting good properties under hot 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. The resulting capacitor assembly may exhibit excellent electrical properties even when exposed to high temperatures.
