An energy‐storage device consisting of polypyrrole (pPy) doped with indigo carmine (IC) and 2,2'‐azinobis (3‐ethylbenzothiazoline‐6‐sulfonate) (ABTS) has been fabricated. These redox‐active conducting polymers (see figure) form the basis of a battery that depends on the faradaic reactions of the redox‐active dopants, and performs better than conventional batteries and ultracapacitors at high power density.
