Chapter 5: Phenothiazine-based Redox Polymers for Energy Storage

Organic redox polymers have received increasing attention as battery electrode materials due to their low toxicity and the possibility to produce them from renewable resources or petroleum. Phenothiazine is a redox-active group with highly reversible redox chemistry. Polymers based on phenothiazine have shown impressive performance as battery cathode materials regarding cycling stability and rate performance. In this chapter, the progress in this field is summarized, specific properties of phenothiazine-based polymers as cathode-active materials are highlighted and future challenges identified.
