Abstract Rechargeable aqueous zinc (Zn) batteries are a promising candidate for large‐scale energy storage, but the noncompact and dendritic Zn deposition, water‐induced parasitic reaction, narrow operating temperature range severely hinder their practical application. Here, it is demonstrated that these challenges can be conquered by introducing low‐cost acetamide (Ace) into electrolytes. The non‐sacrificial Ace molecules with both donor acceptor groups disrupt original H‐bonded network of water, replace solvating‐H 2 O in 2+ ‐solvation sheath, form dynamic adsorption on Zn, create an H O‐poor electrical double‐layer. Consequently, presence suppresses water erosion homogenizes nucleation/growth, reduces reactivity, depresses freezing point electrolyte. formulated Ace‐containing electrolyte features wide from −20 to 60 °C enables highly compact dendrite‐free electrodeposition even at 25 mAh cm −2 using non‐pressure electrolytic cell. Moreover, allows electrodes achieve long‐term lifespan across −20–60 excellent deep cycling stability under 85.3% depth‐of‐discharge (25 ) over 400 h, supports stable operation Zn–Iodine full harsh conditions.

Abstract The reversibility and sustainability of Zn anode are greatly hampered by the dendrite growth side reactions. Orientational deposition, which allows assembly deposits in a highly ordered compact manner, offers solution to these issues enabling dendrite‐free anodes. Moreover, orientational deposition can effectively inhibit reaction reducing exposed surface area electrode. Despite significant progress field there is still lack clear guidelines for regulating orientation, underlying mechanisms remain rather elusive. Therefore, comprehensive review urgently needed provide mechanistic insight into deposition. This summarizes burgeoning strategies steering categorizing corresponding five aspects: heteroepitaxial homoepitaxial interfacial cultivation, crystal facet anchoring, current density regulation. distinct advantages limitations each mechanism controlling orientation discussed detail. Finally, challenges future trends pertaining envisaged, aiming essence realize reversible anodes ultimately bridge gap between reality ideal aqueous Zn‐ion batteries.
