Substituting hydroquinone into polyallylamine allows the resulting organic redox polymer to achieve 99% of its theoretical capacity in aqueous electrolytes. A polymer-air secondary battery fabricated with this redox polymer as the electrode-active material exhibited a constant discharge voltage, high cyclability, and high rate capability. In addition, facile acid treatment decomposes the redox polymer into its raw materials. This work demonstrates a polymer design strategy for integrating typically hydrophobic organic redox molecules into recyclable aqueous batteries.
