Title:
SOLID ELECTROLYTE CAPACITOR AND MANUFACTURING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2014/050913
Kind Code:
A1
Abstract:
This solid electrolyte capacitor (1) is provided with an anode foil (21) on the surface of which an oxide membrane (22) is formed, a cathode foil (23), and a separator (25), and is formed by filling the gap between the anode foil (21) and the cathode foil (23) with a solid electrolyte (26) comprising "conductive microparticles (27) that include a conductive polymer compound, and a hydrophilic polymer compound (28)," wherein the hydrophilic polymer compound (28) includes a structure represented by the chemical formula (I) and a structure represented by the chemical formula (II). -(R1-O)- ... (I) -(R2-O)- ... (II) (In formula (I) and formula (II), R1 and R2 are groups selected from the set consisting of a substituted or unsubstituted alkylene, a substituted or unsubstituted alkenylene, and a substituted or unsubstituted phenylene, and represent mutually different groups.) This solid electrolyte capacitor (1) has high voltage tolerance, low leakage current, and a longer life than conventional examples.
