Popis:	Highlights Intramolecular hydrogen bond regulation is proposed to improve the quinone-based polymer (H-PNADBQ) solubility, conductivity, and kinetics. Intramolecular hydrogen bonds reduce molecular polarization and increase π conjugation level, thereby suppressing the dissolution of the H-PNADBQ and accelerating reaction kinetics of H+/Zn2+ uptake/removal. The H-PNADBQ electrodes exhibit excellent durability with high loading of 5 mg cm−2 and 10 mg cm−2, as well as high rate capability (137.1 mAh g−1 at 25 A g−1).
