“…Lessons from previous research work on the relationship between the zinc crystal plane and zinc deposition behavior point out that zinc metal with the (002) preferred plane is more resistant to dendrite growth than (100) and (101) preferred planes, which may be attributed to the lower deposition rate and electrochemical activity of the (002) plane relative to (100) and (101) planes. − However, exposing specific crystal faces on the zinc sheet surface is difficult. So far, there are only a few reports on homogeneous zinc deposition induced by constructing exposed (002) planes on zinc anodes.…”

The dendrite problem of zinc anodes leads to poor cyclic life and safety hazards, which seriously hinders the development of aqueous zinc-ion batteries (ZIBs). Herein, we propose a new strategy to develop textured zinc anodes with preferential orientation (002) by cleavage fracture along the interface of zinc foil and low lattice mismatched CuZn 5 alloy, which is highly reversible, long-life, and dendrite-free. The sequentially distributed (002) cleavage texture has high surface energy and strong binding energy with zinc atoms, which can significantly reduce the nucleation barrier of zinc and facilitate uniform zinc deposition. Furthermore, the cleavage texture of (002) planes promotes the epitaxial growth of zinc and prevents the dendrite formation. As a result, the zinc anode with the (002) cleavage plane (ZCP (002) ) possesses an ultralong lifetime of about 2500 h in 1 mA cm −2 and 1 mA h cm −2 of symmetric battery and a high average Coulombic efficiency (99.7%) over 925 cycles in ZCP (002) |Cu asymmetric cells. This work provides new insights into modifying metal anodes from the perspective of crystallographic orientation and optimizing zinc anodes for the large-scale application of ZIBs.

Cu (1 1 1) facet exposure can promote zinc nucleation and uniformize zinc growth. [6] The expensive Cu (1 0 0) single-crystal has also been used to inhibit the generation of zinc dendrites. [7] However, there is a limited prospect for graphene, copper nanowires, copper foam, and copper single-crystal because of their high cost. [8] Therefore, it is essential to develop more efficient and low-cost substrate regulation strategies.Electrolytic copper foil is a widely used commercial current collector with mature fabrication technology and acceptable cost. [9] Selective facet exposure during the electrolysis of copper foils has been proven to be easily achievable in existing copper foil preparations. [10] It may be a promising method to prepare specially oriented copper foils by electrolysis for practical applications. Various facets such as (1 1 1), (2 0 0), (2 2 0), and (3 1 1) may be exposed during the copper electrolysis process. [11] If the zinc deposition activity of these facets is identified, zinc deposition can be efficiently regulated by selectively exposing the most active facet. In addition to the effect of substrate facet exposure on zinc deposition, the exposed zinc facets during the deposition process can also influence the subsequent zinc deposition because of the different activities of the different zinc facets. [12] Crystal growth theory suggests that the fast-growing crystalline facets tend to disappear gradually, while slow-growing facets are preferentially exposed. [13] This critical conclusion is usually overlooked by some researchers who determine the preferential growth or exposure of crystal facets only by the intensity of the X-ray diffraction (XRD) peaks. This approach is usually inadequate because the relative peak intensities of bulk samples are related to the grain alignment orientation. [14] Electron backscatter diffraction (EBSD) can be used to precisely analyze the correlation between crystal facet growth and exposure to understand the zinc growth mechanism during electrodeposition. Based on the above considerations, fabrication of copper substrates with high active facet exposure by electrolysis and in-depth study of zinc growth mechanism on substrates are important to enhance its reversibility for zinc plating and stripping.In this work, we reveal the highest zinc deposition activity of Cu (2 2 0) facet in comparison with other low-index crystal facets by optical microscopy and EBSD techniques. An industrial electrolysis method is proposed to construct Cu (2 2 0) substrate with highly preferential orientation, denoted as PCu. This uniformly oriented substrate with zincophilicity can playThe most commonly used zinc foil anode for aqueous zinc-ion batteries suffers from poor cycle stability and low zinc utilization. Zinc-plated anodes on the host materials with high zincophilicity and stability are receiving increasing attention to alleviate these above issues. Here, the high zinc deposition activity of Cu (2 2 0) is confirmed through experimental observations and theoretical cal...
