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.

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.
