摘要： An electrochemical device includes a pair of electrodes and an electrolytic solution. At least one of the pair of electrodes includes an electrode current collector and an electrode material layer supported by the electrode current collector. The electrode material layer includes at least a conductive polymer. A log differential pore volume distribution of the electrode material layer has at least one peak in a range of a pore diameter of more than or equal to 50 nm.

摘要： An electrolytic capacitor includes at least one capacitor element. The at least one capacitor element includes: an anode body including an anode lead portion, and a cathode forming portion; a dielectric layer disposed on at least a surface of the cathode forming portion of the anode body; and a cathode part covering at least a part of the dielectric layer. The cathode part includes a solid electrolyte layer that contains a conductive polymer, and covers at least a part of the dielectric layer. A ratio T1/T2 of a thickness T1 of the solid electrolyte layer formed at a corner portion of the anode body to a thickness T2 of the solid electrolyte layer formed at a center portion of a principal surface of the anode body is in a range from 0.8 to 1.7, inclusive, in a cross section of the at least one capacitor element.

摘要： An electrochemical device includes a positive electrode and a negative electrode. The positive electrode for the electrochemical device includes a positive current collector, and an active layer including a conductive polymer disposed on the positive current collector. The conductive polymer contains a polyaniline or a derivative of polyaniline. An infrared absorption spectrum of the active layer exhibits a peak derived from a carbonyl group. The peak derived from the carbonyl group appears, for example, in a range from 1600 cm−1 to 1700 cm−1, inclusive.

摘要： An electrochemical device electrode includes a conductive polymer as an active material. The conductive polymer has a grain shape, and an intensity distribution pattern obtained by X-ray diffraction measurement with respect to the conductive polymer has a first peak in which a diffraction angle 2θ ranges from 18° to 21°, inclusive, and a second peak in which a diffraction angle 2θ ranges from 24° to 26°, inclusive.
