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 peak derived from a carbonyl group. The peak derived from the carbonyl group appears, for example, in a range from 1600 cmto 1700 cm, inclusive.
