“…2(d)). [45][46][47]73 In turn, the reaction mechanisms involved mainly deal with functional group interaction and polarization induction, which is slightly different from that of the (002) orientational deposition mode. Collectively, these fascinating observations necessitated us to explore the emerging strategies in steering Zn orientational deposition and analyze the current understanding of structure-performance relationships in the following context (Fig.…”

“…The thus-etched Zn foil would feature an exposed large number of (002) planes. 71,73,[103][104][105] Besides this, the surface energy decrease of a crystal plane offers a fascinating avenue by which to realize planar Zn deposition. For this purpose, emerging materials with specific atoms and functional groups that can interact strongly with Zn could come into play.…”

“…[11] Recent studies have shown that achieving compactly and horizontally aligned Zn deposition with (002) crystallographic texture is essential to address these two issues and to boost the reversibility and lifespan of the Zn metal anode. [12][13][14][15][16][17][18] The morphology of Zn electrodeposits can be significantly affected by the mass transport at the electrode-electrolyte interface. Mossy, compact or dendritic morphologies were reported based on different electroplating parameters, such as current densities, [19][20][21] overpotentials, [22] and electrolyte concentrations.…”

Nonepitaxial Electrodeposition of (002)‐Textured Zn Anode on Textureless Substrates for Dendrite‐Free and Hydrogen Evolution‐Suppressed Zn Batteries

Nontoxic and safe aqueous Zn batteries are largely restricted by the detrimental dendrite growth and hydrogen evolution of Zn metal anode. The (002)‐textured Zn electrodeposition, demonstrated as an effective approach for solving these issues, is nevertheless achieved mainly by epitaxial or hetero‐epitaxial deposition of Zn on pre‐textured substrates. Herein, the electrodeposition of (002)‐textured and compact Zn on textureless substrates (commercial Zn, Cu, and Ti foils) at a medium‐high galvanostatic current density is reported. According to the systematic investigations on Zn nucleation and growth behaviors, this is ascribed to two reasons: i) the promoted nonepitaxial nucleation of fine horizontal (002) nuclei at increased overpotential and ii) the competitive growth advantages of (002)‐orientated nuclei. The resulting freestanding (002)‐textured Zn film exhibits significantly suppressed hydrogen evolution and prolonged Zn plating–stripping cycling life, achieving over 2100 mAh cm−2 cumulative capacity under a current density of 10 mA cm−2 and a high depth of discharge (DOD) of 45.5%. Therefore, this study provides both fundamental and practical insights into long‐life Zn metal batteries.

“…The (002) plane of Zn crystals is grown layer by layer, as reflected in Figure 3g, and endows uniform and dendrite-free electrodes to achieve long-cycling plating and stripping performance. [38] The XPS analysis of the P-Zn electrode after 50 cycles shows that the F elemental proportion is 6.2% (Table S1, Supporting Information), most of which is ionic F (Figure 3h), indicating an abundance ZnF 2 formed on the surface. The top-layer of the ZnF 2 forms SEI, which can efficiently suppress the HER and improve Zn reversibility.…”

Aqueous Zn metal-based batteries have considerable potential as energy storage system; however, their application is extremely limited by dendrite development and poor reversibility. In this study, to overcome both challenges, F-doped carbon nanoparticles (FCNPs) are uniformly constructed on substrates (Ti, Zn, Cu, and steel) by a plasma-assisted surface modification, which endows reversible and uniform deposition of Zn metal. FCNPs with high surface charge density act as nucleation assistors and form numerous homogenous Zn nucleation sites toward Zn 3D growth, which improves Zn plating kinetic and results in uniform Zn deposition. Furthermore, the ZnF 2 solid electrolyte interface generated during cycling contributes to rapid mass transfer and enhances Zn reversibility, but also suppresses the side reaction. Accordingly, the half-cell of P-Ti coupled with Zn exhibits an average Coulombic efficiency of 99.47% with 500 cycles. The symmetric cell of the P-Zn anode presents a lifespan of over 1500 h at the current density of 5 mA cm −2 . Notably, the cell works for 100 h at 50 mA cm −2 . It is believed that this ingenious surface modification broadens revolutionary methods for uniform metallic deposition, as well as the dendrite-free rechargeable batteries system.
