Specifically, under mediation 100‐ECR, electroplated configures oriented dense deposition texture, slows down formation dendrites. Furthermore, owing high resistance protective interface formed by adsorbed ECR on electrode surface, anode demonstrates enhanced reversibility higher Coulombic efficiency modified electrolyte. Consequently, superior electrochemical performance achieved through novel control strategy protection technology.

Abstract Zincophilic additives have been widely applied to stabilize Zn metal anodes owing their efficacy in regulating 2+ diffusion. However, high zincophilicity causes elevated desolvation barriers, contributing increased polarization and reduced stability, particularly under high‐current conditions. Herein, a novel molecular engineering approach is proposed that integrates steric hindrance H‐bond interactions promote the of zincophilic additives, thereby achieving high‐rate with minimized polarization. As proof‐of‐concept, N,N‐di‐(2‐picolyl)ethylenediamine (NDPA), additive comprising potent chelating sites polar amino tail group designed. NDPA boasts four solvation sites, which not only contribute exceptional zincophilicity, effectively diffusion but also exhibit significant hindrance, reducing number H₂O molecules, lowering dehydration energy. Additionally, NDPA's free groups form H‐bonds facilitating dissociation coordinated additives. Consequently, at current density 20 mA cm −2 , addition Zn||Zn symmetric cell improves lifespan from 37 h over 2000 reduces voltage 137 82 mV. This work presents strategy overcome zincophilicity‐desolvation dilemma electrolyte for developing durable zinc anodes.
