Highlights Developed a versatile HT-based redox polymer electrolyte with exceptional ionic conductivity (73.5 mS cm−1) through self-exchange reaction-based ion hopping mechanism and enhanced polymer chain mobility. Achieved superior electrochemical performance (25.4 Wh kg−1 at 25,000 W kg−1) in fiber-shaped energy storage devices without additional active materials by utilizing HT as both ionic conductor and redox-active species.
