Abstract
Organic electrode materials hold great promise for advancing the development of aqueous batteries due to their structural diversity and sustainability. However, they still encounter challenges such as low electroactive mass contribution and undesirable cycling performance resulting from intrinsic poor electronic conductivity. Herein 1, 2-dihydroxyphenazine (DHP) was designed based on phenazine. Compared with the negative electrode of phenazine, the introduction of hydroxyl groups can reduce the redox potential by 0.2 V. The fast transport channel formed by intramolecular hydrogen bonding can significantly improve the redox kinetics. The optimized DHP‖Ni(OH)2 battery has a discharge capacity of 240 mAh/g and a high energy density over 50 Wh/kg.
