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.
