“…Upon plating, the in uences of external factors often promote the preferred orientation of Zn grains along a speci c crystal plane, thus leading to a speci c morphological "texture" [21][22][23] . The morphology and texture of Zn deposits have been proved to be closely related to additives 22,[24][25][26] , initial substrate composition and texture 5,27,28 , and applied external elds 19,29 . Organic molecules and additives can adsorb on a Zn surface, guiding the Zn deposits to show speci c preferred orientation of crystal planes 25,26,30 .…”

Rechargeable aqueous zinc-ion batteries (RZIBs) provide a promising complementarity to the existing lithium-ion batteries due to their low cost, non-toxicity and intrinsic safety. However, Zn anodes suffer from zinc dendrite growth and continuous unfavorable side reactions, resulting in low Coulombic efficiency (CE) and severe capacity decay. Here, we develop an ultrathin, fluorinated two-dimensional porous covalent organic framework (FCOF) film as a protective layer on the Zn surface to address these issues. The strong interaction between fluorine (F) in FCOF and Zn reduces the surface energy of the Zn (002) crystal plane and regulates planar growth of zinc anode materials. As a result, Zn deposits underneath FCOF films show parallel platelet morphology with (002) planar orientations preferred. Furthermore, F-containing nanochannels facilitate the de-solvation of hydrated Zn ions and prevent electrolyte penetration, thus retarding corrosion of Zn. Such unique FCOF films prolonged the Zn symmetric cell lifespan to over 1700 h, which is 13 times longer than the cells without protection (125 h). The assembled full cells demonstrate a cycle life of over 250 cycles at 3 mAcm-2 under practical conditions, including lean electrolyte (12 μLmAh-1), limited Zn excess (only 1×excess), and a high mass loading of MnO2 cathode (16 mgcm-2). This work provides a new perspective for the realization of planar deposition of zinc metal anodes for developing high performance Zn-based batteries.

To investigate the effect of the surface texture of steel on the crystal orientation relation between Fe and Zn, we deposited Zn at 1500 A m −2 and 1.48 × 10 4 C m −2 onto both Al killed and IF steel sheets in an agitated sulfate solution at 313 K. Chemically polishing the steel simpli es the deposition of Zn epitaxially because of the decreased strain in the steel surface. For Zn deposited on Al killed steel, the Burgers orientation relation of {110}Fe//{0001}Zn was completed after the chemical polishing of the steel. In this case, because the orientation of {111}Fe increased and Zn was deposited according to the orientation relation of {110}Fe//{0001}Zn, the orientation of {0001}Zn decreased. In contrast, for Zn deposited on IF steel, the preferred relation was {111}Fe//{0001}Zn. The crystal grain size of IF steel is larger than that of Al killed steel, which makes the epitaxial growth of Zn easier on IF steel than on Al killed steel. The orientation of {111}Fe was more prominent in IF steel than in Al killed steel. Because the proportion of {0001}Zn increases under conditions where the epitaxial growth of Zn occurs easily and the orientation {111}Fe was more prominent in IF steel, this appears to be the cause of the relation of {111}Fe//{0001}Zn. The orientation relation between the deposited Zn and steel changes based on the strain, crystal orientation, and grain size of the steel. Therefore, the crystal orientation of the deposited Zn changes as well.
