Title:
SEPARATOR FOR SOLID ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2020/196215
Kind Code:
A1
Abstract:
The problem of the present invention is to provide a separator for a solid electrolytic capacitor having high heat resistance, for which there is little thickness unevenness, internal short circuits do not occur easily, and impedance is not too high. In the separator for a solid electrolyte capacitor comprising nonwoven fabric, the separator for a solid electrolytic capacitor is characterized in that the nonwoven fabric contains fibrillated heat resistant fiber and synthetic staple fiber as essential components, and the proportion of the fibrillated heat resistant fiber for which the fiber length of the fibrillated heat resistant fiber is 0.30 to 0.75 mm and the fiber width is 12 to 40 µm is 55% or greater and less than 75%.
