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 cm−1 to 1700 cm−1, inclusive.
Claims5
A positive electrode for an electrochemical device, the positive electrode comprising:
- a positive current collector, and
- an active layer including a conductive polymer disposed on the positive current collector, wherein:
- the conductive polymer contains a polyaniline or a derivative of polyaniline,
- an infrared absorption spectrum of the active layer exhibits a peak derived from an amide-linked carbonyl group, and
