Beschreibung
Zusammenfassung:	A positive electrode active material for an electrochemical device has a fiber shape or a grain-aggregate shape. The positive electrode active material includes an inner core part having a fiber shape or a grain-aggregate shape, and a superficial part covering at least part of the inner core part. The inner core part contains a first conductive polymer, and the superficial part contains a second conductive polymer that is different from the first conductive polymer.
