Rechargeable aqueous Zn-ion batteries (ZIBs) have gained great attention due to their high safety and the natural abundance of Zn. Unfortunately, the Zn metal anode suffers from dendrite growth due to nonuniform deposition during the plating/stripping process, leading to a sudden failure of the batteries. Herein, Cu coated Zn (Cu–Zn) was prepared by a facile pretreatment method using CuSO4aqueous solution. The Cu coating transformed into an alloy interfacial layer with a high affinity for Zn, which acted as a nucleation site to guide the uniform Zn nucleation and plating. As a result, Cu–Zn demonstrated a cycling life of up to 1600 h in the symmetric cells and endowed a stable cycling performance with a capacity of 207 mAh g−1even after 1000 cycles in the full cells coupled with a V2O5-based cathode. This work provides a simple and effective strategy to enable uniform Zn deposition for improved ZIBs.Keywords:zinc metal anode;copper coating;alloy interfacial layer;uniform Zn deposition;aqueous zinc-ion battery

The synergistic “anchor-capture” mechanism of polar groups on Zn stripping/plating process is firstly proposed.
The amino group firmly anchors on Zn surface and the carboxyl group strongly captures Zn 2+ , constructing a robust anode–electrolyte interface and inducing uniform Zn deposition.
The ultra-stable cycle lifespan of Zn–Zn symmetric cell (over 2800 h) and high utilization rate of Zn anode (the depth of discharge up to 68% for 200 h) are achieved under the proposal of synergistic “anchor-capture.”

Zn ion capacitors (ZICs) composed of a carbon-based cathode and a Zn anode are one of the most promising energy storage devices due to their inherent safety and high-power output. However, their poor cycling stability originating from the Zn dendrites’ formation and low energy density limited by insufficient activated carbon properties remain major challenges for development of high-performance ZICs. Hence, we constructed a facile and effective strategy to alleviate “edge effects” and suppress Zn dendrites by growing ZnO nanowire arrays on Zn foil (ZnO@Zn) using a horizontally potentiostatic anodizing technique. The electrochemical characterizations and in situ optical microscopy observation revealed that the introduction of ZnO nanowire arrays can significantly suppress the growth of Zn dendrites and enhance the cycling stability of the Zn anode. The superfine and interlaced ZnO nanowire arrays provide uniform nucleation sites and high electrical conductivity for the Zn metal anode, reducing the local current density and promoting the rapid diffusion and migration of Zn ions on the Zn anode surface. As a result, the ZnO@Zn electrode has a very low nucleation overpotential and excellent cycle stability, far superior to the bare Zn anode. Furthermore, a ZnO@Zn//NPHC ZIC assembled with an N, P-codoped hard carbon (NPHC) cathode delivers a high specific capacity of 110.3 mAh g–1 at 0.1 A g–1 and achieves outstanding cycling stability with 90% capacity retention together with ∼100% Coulombic efficiency after 20000 cycles.

Aqueous rechargeable zinc ion batteries (ARZIBs) are ideal for massive and longstanding energy storage applications because of their excellent security and low operation cost. Nevertheless, ARZIBs are subject to the severe corrosion reaction of zinc metal anodes that is derived from the thermodynamic unsteadiness of the zinc anodes in aqueous solution, as well as zinc dendrite growth originating from uncontrolled zinc deposition. Herein, we created a separator by coating a thin piece of polypropylene (PP) with a compound consisting of zinc trifluoromethanesulfonate [Zn(OTf)2] and poly(vinylidene fluoride-hexafluoropropylene (PVDF-HFP). Consequently, the severe corrosion reaction of the zinc metal anodes and the profuse formation of zinc dendrites were effectively mitigated by the novel PP separator, which prolonged the lifetime of the zinc metal anodes. When a zinc metal plating layer was used with preferential (002) crystallographic orientation, the cyclic performance over 1100 h of the symmetrical Zn∥Zn battery based on the novel separator was steady. Additionally, the Zn∥MnO2 batteries exhibited an impressive specific capacity and competitive long durability of 75.5% over 500 cycles at a current density of 0.1 A g−1. With this work, we intend to set the standard for designing novel separators in the construction of advanced zinc anodes for high-performance ARZIBs.

The performance of aqueous zinc-ion batteries is frequently hindered by anode-related issues such as uncontrolled dendrite formation and side reactions. Metal–organic frameworks (MOFs), characterized by their highly ordered porous structures, remarkably large specific surface areas, and tunable active sites, offer a promising solution by regulating Zn2+ flux and promoting uniform Zn deposition. In this study, a Cu-MOF was synthesized in situ on carbon cloth (CM-C) and functioned as an ion-buffering layer within the battery. This innovative configuration significantly mitigates side reactions, achieving an extended cycle life of nearly 800 h at a high current density of 10.0 mA cm–2 (areal capacity: 10.0 mA h cm–2) and nearly 1200 h at 5.0 mA cm–2. After 2000 cycles at 5.0 mA cm–2, the battery demonstrated an average Coulombic efficiency of 99.3%. Additionally, the full battery containing CM-C demonstrated enhanced capacity and stability. This simple and novel structure provides new possibilities for enhancing the cycling stability of zinc-ion batteries.

To determine whether high spraying concentrations of Zn sources increase the Zn concentration in waxy corn ( Zea mays L. var. ceratina Kulesh) seeds without compromising agronomic performance, field experiments were conducted between 2018 and 2020. Excess ZnSO 4 application caused foliar burn, barren ear tip, and grain yield loss. ZnEDTA and Glycine-chelated Zn (ZnGly) caused less foliar burn, but Glycine-mixed Zn caused more foliar burn than ZnSO 4 . The seed Zn concentration increased with spraying Zn concentration. ZnEDTA (≤0.8%) had a higher threshold concentration than ZnGly (≤0.4%). Nevertheless, Zn biofortification efficacy did not significantly differ between 0.4% ZnGly and 0.8% ZnEDTA, and the grain Zn recovery rate of 0.4% ZnGly was much higher than that of 0.8% ZnEDTA. Additionally, dual-isotope labelling tests confirmed that 15 N-glycine and 68 Zn in ZnGly interacted. In the future, chelating technology is essential for developing new Zn fertilizers to optimize Zn biofortification efficacy.

Multifunctional interfacial construction of zinc metal anodes is a crucial measure to surmount the uncontrolled dendrite growth and intricate side reactions. Herein, an organic polymer film formed by the complexation effect between polyacrylonitrile (PAN) and zinc acetate is introduced on a zinc metal to prepare zinc complex polyacrylonitrile@Zn electrode (PANA@Zn). This PANA layer functions as a stretchy barrier to restrain the side reaction and repress zinc dendrites. More importantly, the zinc ion kinetics of PANA layer can be controlled by the complexation states between Zn species and C=N bond along with the heating time, which can regulate the zinc ion flux distribution, resulting in fast and uniform zinc deposition. Thanks to this multifunction protective layer, the obtained PANA@Zn electrode is given a stable cycling lifespan of 3000 h at 1 mA cm −2 (polarization voltage of 46 mV). Furthermore, the convincing performances are also displayed in full cells, which involves 179 mAh g −1 after 700 cycles at 1 A g −1 for CNT/MnO 2 ||PANA@Zn full cell, indicating the feasibility of this multifunction shielded layer for the application in zinc metal anode.

Zinc-ion hybrid capacitors (ZIHCs) with high energy density is commercial need as energy storing devices, but facile preparation is still a challenge. Herein, we proposed a combined strategy for preparation of ZIHCs with high performance. For this purpose, a nanoemulsion assembly approach with Pluronic F127 as structure-directing agent, 1, 3, 5-trimethylbenzene as pore-expanding agent, polydopamine as carbon and nitrogen source, was used to synthesize hierarchically N-doped porous carbon spheres (N-HNCSs). The optimized sample of N-HNCS-1 exhibited uniform size of 150 nm, hierarchically porous structure, large surface area (705.46 m 2 g −1 ), and N-doping amount of 6.51 %. These properties were beneficial for the transportation of the electrolyte ions resulted in that the N-HNCS-1 electrode displayed superior electrochemical performance with specific capacity of 142 mAh g −1 . Furthermore, the Zn//ZnSO 4 + ZnI 2 //N-HNCS-1 ZIHCs achieves an exceptionally high energy density of 347.7 Wh kg −1 , which is 3-fold higher than that of Zn//ZnSO 4 //N-HNCS-1 ZIHCs. To elucidate this outstanding performance, we investigate the mechanisms involved, including Zn 2+ deposition/stripping, SO 4 2- /I - adsorption/desorption, Zn 4 SO 4 (OH) 6 ⋅0.5 H 2 O precipitation/dissolution, and redox reactions relating to iodine ions . The incorporation of ZnI 2 redox-electrolyte significantly enhanced the energy density by providing prominent pseudocapacitance via the faradaic reaction. Therefore, the high performance of Zn//ZnSO 4 + ZnI 2 //N-HNCS-1 ZIHCs is attributed to the introduction of nitrogen (N) species, advantageous 3D carbonaceous framework, and redox reactions triggered by adding zinc iodide (ZnI 2 ) into the aqueous zinc sulfate (ZnSO 4 ) electrolyte. This groundbreaking research opens up possibilities for the development of high-energy ZIHCs, and advancements in energy storage technology.

Graphical The zinc anode was modified by constructing a silica aerogel layer with ultra-high specific surface area and abundant polar functional groups (−OH, −COOH, −CH 3 ), which not only provided abundant active sites for the uniform deposition of zinc ions, but also mitigated the dissolution of Zn 2+ in the electrolyte and successfully suppressed the zinc dendrites and the related side reactions, thus improving the stability of the zinc metal anode. Aqueous zinc ion batteries have the advantages of low cost, high safety, high theoretical specific capacity. However, the charging and discharging process is usually accompanied by side reactions such as dendrite growth, hydrogenolysis, corrosion of electrodes, passivation, etc., which limits the development and application. In this work, the zinc anode is modified by constructing a silica aerogel layer with ultra-high specific surface area and abundant polar functional groups (−OH, −COOH, −CH 3 ), which not only provides abundant active sites for the uniform deposition of zinc ions, but also construct an artificial protective layer that acting as a desolvation layer and a zinc ion flux regulator. Consequently, the altered zinc anode exhibits an extremely durable zincophilic characteristic and a declining interfacial impedance. The constructed artificial layer can prevent side reactions and promote uniform zinc ion deposition to prevent the generation of zinc dendrites during the charge/discharge process. Results show that the symmetric cells composed of modified Zn anodes can be stably cycled for more than 1100 h at 0.5 mA cm −2 and 0.5 mAh cm −2 , which is much higher than that of bare Zn. In addition, the life and capacity retention of the Zn/MnO 2 full cells were also significantly improved.

Aqueous zinc-ion batteries have attracted widespread attention due to their low cost and high safety. Unfortunately, their commercial applications are greatly inhibited by the negative effects of zinc dendrites and side reactions. A solution that utilizes a 3D host can help mitigate these issues. In this paper, we present a 3D host that is composed of an aerogel scaffold with a poly(vinyl alcohol) and MXene structure. The embedded Zn can be densely packed inside the host due to its zincophilic properties. During cycling, the fluorine-based functional groups on the surface of MXene were able to react with the electrolyte to form the ZnF2 solid electrolyte interphase, which can effectively protect the composite anode. As a result, the symmetrical battery was capable of stable cycling for >300 h at a high current density of 10 mA cm–2. More impressively, the assembled full cell retained 93.86% after 800 cycles at a current density of 5 A g–1. This work provides an effective idea for improving the cycling performance of aqueous zinc-ion batteries.

Zinc (Zn) metal is considered the promising anode for “post-lithium” energy storage due to its high volumetric capacity, low redox potential, abundant reserve, and low cost. However, extravagant Zn is required in present Zn batteries, featuring low Zn utilization rate and device-scale energy/power densities far below theoretical values. The limited reversibility of Zn metal is attributed to the spontaneous parasitic reactions of Zn with aqueous electrolytes, that is, corrosion with water, passive by-product formation, and dendrite growth. Here, a new ion-selective polymer glue coated on Zn anode is designed, isolating the Zn anode from the electrolyte by blocking water diffusion while allowing rapid Zn 2+ ion migration and facilitating uniform electrodeposition. Hence, a record-high Zn utilization of 90% is realized for 1000 h at high current densities, in sharp contrast to much poorer cyclability (usually < 200 h) at lower Zn utilization (50–85%) reported to date. When matched with the vanadium-based cathode, the resulting Zn-ion battery exhibited an ultrahigh device-scale energy density of 228 Wh kg −1 , comparable to commercial lithium-ion batteries.

Optimizing Zn 2+ dispersion and regulating Zn 2+ deposition is a key issue in the aqueous Zn-ion anodes. Herein, the flexible membrane (CNT/PAN/Ag) with uniformly interwoven pores was facilely fabricated by one-step phase inversion method. The complex woven pore structure can effectively disperse the flow of Zn 2+ , reduce current density of nucleation sites, and avoid the aggregated deposition of Zn 2+ . Furthermore, the scalable Janus membrane with different affinities to electrolyte on the two sides can be designed based on the membrane surface structure. The high wettability of the upper surface of the membrane with electrolyte facilitates rapid transfer of Zn 2+ flux into the membrane for redispersion, and low wettability of the back surface is benefit to isolate electrolyte from surface of the zinc anode and to avoid side reactions brought about by the aqueous electrolyte. Meanwhile, by virtue of the high adsorption energy with Zn 2+ , the doped Ag active sites in the membrane further extend the dispersion path of Zn 2+ within the membrane and induce portion of Zn 2+ to be deposited within the membrane, balancing and reducing current density at the deposition interface. In the galvanostatic current test of the symmetric battery at 1 mA cm −2 , 0.5 mAh cm −2 , the battery can be stably cycled more than 1000 h, the specific capacity of pouch cell with NH 4 V 4 O 10 reserved 384 mA h/g at 5 Ag −1 after 95 cycles. The work presents a new flexible membrane design for solving the Zn dendrites in aqueous zinc ion batteries.
