Abstract
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 first peak derived from a quaternized nitrogen atom of the polyaniline or the derivative of polyaniline, and a second peak derived from a benzenoid structure of the polyaniline or the derivative of polyaniline. And a ratio of an absorbance of the first peak to an absorbance of the second peak is more than or equal to 0.3.
