Abstract Aqueous zinc–sulfur (Zn─S) batteries represent a promising technology for grid‐scale energy storage because of the advantages environmental friendliness, low cost, and high theoretical capacity. However, practical applications Zn─S are hindered by sluggish oxidation kinetics zinc sulfide (ZnS) during charge process. Herein, strategy nucleophilic regulation is proposed to modulate ZnS adjusting bonding strength. By screening different groups, it found that tetramethylene sulfone (TMS) can not only strongly interact with Zn atoms through group lower barrier but also effectively suppress side reactions shielding from active water molecules, thus facilitating complete conversion sulfur. Benefiting these advantages, aqueous assembled TMS as multifunctional electrolyte additive demonstrate superior specific capacity 799 mAh g −1 at current density 2.0 A 649 4.0 an enhanced retention after long cycles. This work demonstrates promise modulating cathode reaction in beyond.
