Abstract Zinc metal stands out as a promising anode material due to its exceptional theoretical capacity, impressive energy density, and low redox potential. However, challenges such zinc dendrite growth, corrosion, side reactions in aqueous electrolytes significantly impede the practical application of anodes. Herein, 3‐(1‐pyridinio)‐1‐propanesulfonate (PPS) is introduced zwitterionic additive achieve long‐term highly reversible Zn plating/stripping. Due orientation polarization with force electric field, PPS π–π conjugated pyridinio cations strong coordination ability sulfonate anion tends generate dynamic adsorption layer build unique water–poor interface. steric hindrance effect can attract solvated 2+ , thereby promoting desolvation process. Moreover, by providing large number nucleation sites inducing ion flow, preferred (002) crystal plane be achieved. Therefore, interfacial electrochemical reduction kinetics regulated uniform deposition ensured. Owing these advantages, Zn//Zn symmetrical cell exhibits remarkable cycling stability exceeding 2340 h (1 mA cm −2 1 ). The Zn//V 2 O 5 full also delivers stable for up 6000 cycles.

Abstract The potential for scale‐up application has been acknowledged by researchers rechargeable aqueous zinc‐ion batteries (ZIBs). Nonetheless, the progress of development is significantly impeded due to instability interface between zinc anode and electrolyte. Herein, efficient environmentally benign valine (Val) were introduced as electrolyte additive stabilize electrode/electrolyte (EEI) via functional groups in molecules, thus achieving reversible dendrite‐free anode. amino present Val molecules have a strong ability adsorb on surface metal, enabling construction anchored molecular layer anodes. strongly polar carboxyl can act ion‐transport pumps capture ions electric double (EDL) through coordination chemistry. Therefore, this reconstructed EEI could modulate ion flux simultaneously suppress side reactions dendritic growth Zn. Consequently, long stable cycling up 1400 h at high current density 20 mA cm −2 achieved. Additionally, Zn//V 2 O 5 full cell with exhibit enhanced cyclability, retaining 77 % capacity after 3000 cycles, displaying significant promoting commercialization ZIBs.
