Organic redox polymers are characterized by a large population of redox-active electron-releasing and -gaining sites that allow efficient redox-gradient-driven electron-or charge-transport and storage throughout the polymer layer via electron self-exchange reactions. Typically, the redox-active sites are quinones, imides, viologens, and organic robust radicals such as nitroxides and galvinoxyl. The polymers give rise to high current density over 1 A/cm2 to allow a rapid charging capability which has relevance to high-density energy storage with excellent cyclability in electrode performance. Targets of their application include organic-based, high-power and flexible batteries.
