SOLID ELECTROLYTE CAPACITOR AND MANUFACTURING METHOD FOR SAME

摘要

A solid electrolyte capacitor includes an anode foil on a surface of which an oxide film is formed, a cathode foil, and a separator. A gap between the anode foil and the cathode foil is filled with a solid electrolyte which contains a conductive fine particles containing a conductive polymer compound and a hydrophilic polymer compound. The hydrophilic polymer compound has a structure expressed by a following chemical formula (I) and a structure expressed by a following chemical formula (II).;—(R1—O)—  (I);—(R2—O)—  (II);In the formula (I) and the 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.

1. A solid electrolyte capacitor comprising:
an anode foil on a surface of which an oxide film is formed; a cathode foil; and a separator disposed between the anode foil and the cathode foil, wherein a gap formed between the anode foil and the cathode foil is filled with a solid electrolyte which contains a conductive fine particles containing a conductive polymer compound and a hydrophilic polymer compound, when a defect occurs in the oxide film, moisture which the hydrophilic polymer compound retains can be used for repairing the defect, and the hydrophilic polymer compound has a structure expressed by a following chemical formula (I) and a structure expressed by a following chemical formula (II).
—(R1—O)—  (I)—(R2—O)—  (II)(In the formula (I) and the 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).
