Uneven Zn deposition and unfavorable side reactions have prevented the reversibility of the Zn anode. Herein, we design a rearranged (002) textured Zn anode inspired by a traditional curvature-enhanced adsorbate coverage (CEAC) process to realize the highly reversible Zn anode. The rearranged (002) textured structure directs superconformal Zn deposition by controlling the spatial deposition rate of the rearranged crystal planes, thereby promoting bottom-up “superfilling” of the 3D Zn skeletons. Meanwhile, our designed anode also induces the epitaxial Zn deposition, alleviating the parasitic reactions owing to the lowest surface energy of the (002) plane. Attributed to these superiorities, uniform and oriented Zn deposition can be obtained, exhibiting an ultra-long lifespan over 479 hrs at an ultrahigh depth of discharge (DOD) of 82.12 %. The Zn | Na₂V₆O₁₆ ⋅ 3H₂O battery delivers an improved cycling performance, even at a high area capacity of 5.15 mAh/cm² with a low negative/positive (N/P) capacity ratio of 1.63. The superconformal deposition approach for Zn anodes paves the way for the practical application of high-performance zinc-ion batteries. 

Graphical Abstract

A re-arranged (002) textured Zn anode in Zinc-ion-Batteries. We design a rearranged (002) textured Zn anode inspired by a curvature-enhanced adsorbate coverage (CEAC) process to realize a highly reversible Zn anode for high-performance zinc-ion batteries. The spatially re-arranged crystal planes induce the superconformal Zn deposition and the epitaxial Zn deposition along (002) orientations and alleviate the parasitic reactions.
