Abstract The poor anode/electrolyte interface triggered by abysmal dendritic growth and hydrogen evolution reactions (HER) hinders the development of aqueous zinc‐ion batteries (AZIBs). Here, a highly efficient electrolyte is formulated with sucralose (Sucral) additive to refresh solvated structure steer interfacial renovation, for building electronegative Cl‐modulated trinity effect in bulk‐interface between electrode. Experiment results theoretical studies jointly reveal that Sucral zincophilic hydrophilic hydroxyl groups can remodel primary Zn 2+ solvation shell interrupt strong H‐bond network from H 2 O molecules, thus boosting fast de‐solvation restricting undesirable HER. Simultaneously, three chlorides adsorbed possessing hydrophobic features enable O‐poor electric double‐layer (EDL), remodeling surface against corrosion. Additionally, it realizes preferential exposure (002) plane helping uniform deposition. synergy above factors achieves prolonged lifespan 3000 h (1.0 mA cm −2 , 1.0 mAh ), much better than Sucrose (Suc) electrolyte. Zn//V 5 full cell at A g −1 also maintains enhanced stability 1500 cycles 160 .

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 To address the issues of dendrite growth and zinc corrosion in rechargeable zinc‐air batteries, multifunctional glycine/valine additives are introduced into electrolyte. By regulating solvation shell structure enhancing interfacial stability, these aim to protect reversibility stability anode. Glycine/valine molecules inhibit formation [Zn(H 2 O) 6 ] 2+ Zn 5 (OH) 8 (OAc) ·2H O by‐products at interface by replacing active water a strong alkaline environment. Additionally, they form hydrophobic electric double layer on metal surface, during charge/discharge process, construct an situ solid electrolyte layer. This further suppresses hydrogen evolution reaction growth. The superior long‐term cycling Zn||Zn cells, Zn||Cu, full cells demonstrates effectiveness additives.
