The inherent shortcomings of a zinc anode in aqueous zinc-ion batteries (ZIBs) such as zinc dendrites and side reactions severely limit their practical application. Herein, to address these issues, an ion-oriented transport channel constructed by graphdiyne (GDY) nanowalls is designed and grown in situ on the surface of a zinc electrode. The vertically stacked GDY nanowalls with a unique hierarchical porous structure and mechanical properties form a nanomesh-like interface on the zinc electrode, acting as an ion-oriented channel, which can efficiently confine the segmented growth of zinc metal in microscopic regions of hundreds of nanometers. In those microscopic regions, the uniform domain current density is effortlessly maintained compared with a large surface area, thereby inhibiting zinc dendrites effectively. Besides, due to the presence of the ion-oriented channel, the modified zinc anode demonstrates long-term stable zinc plating/stripping performance for more than 600 h at 1 mAh cm −2 in an aqueous electrolyte. In addition, full-cells coupled with MnO 2 show high specific capacity and power density, as well as excellent cycling stability with a capacity retention of 82% after 5000 cycles at 1 A g −1 . This work provides a feasible and accessible surface engineering approach to modify the electrode interface for confined and dendrite-free zinc deposition in aqueous ZIBs.

Aqueous zinc-ion batteries offer the greatest promise as an alternative technology for low-cost and high-safety energy storage. However, the development of high-performance cathode materials and their compatibility with aqueous electrolytes are major obstacles to their practical applications. Herein, we report the synthesis of orthorhombic V2O5·nH2O nanorods as cathodes for aqueous zinc batteries. As a result, the electrode delivers a reversible capacity as high as 320 mAh g−1at 1.0 A g−1and long-term cycling stability in a wide window of 0.2 to 1.8 V using a mild ZnSO4aqueous electrolyte. The superior performance can be attributed to the improved stability of materials, inhibited electrolyte decomposition and facilitated charge transfer kinetics of such materials for aqueous zinc storage. Furthermore, a full cell using microsized Zn powder as an anode within capacity-balancing design exhibits high capacity and stable cycling performance, proving the feasibility of these materials for practical application.Keywords:zinc batteries;V2O5·nH2O nanorods;cathode materials;Zn anode;aqueous batteries

In this study, a low-cost and friendly compound diazolidinylurea carrying a number of heteroatoms and inter/intra hydrogen bonding, a derivative of urea (DU), efficiently strengthened aqueous zinc ions batteries (AZIBs) in ZnSO4 electrolyte. The influence of DU on the zinc anode in the 2 M ZnSO4 electrolyte was fully studied by various surface chemistry and electrochemistry means. It is demonstrated that the super low concentration of DU (2 mM, 0.00556 wt %) could inhibit the formation of zinc dendrites, zinc corrosion, and the hydrogen evolution reaction during the constant current cycling of water system ZIBs, which thus enabled symmetric zinc–zinc batteries to reach a cycle life of 7336 h (nearly 306 days) under 1 mA·cm–2, 1 mA h·cm–2 at 25 °C and 426 h (nearly 18 days) at 55 °C, and inspired zinc–manganese full battery to maintain a capacity retention rate of more than 52% after cycling for 1000 cycles under a current of 2 A·g–1. These results are much superior over zinc ion cells based on the blank ZnSO4 batteries. Even if the Zn–Cu half cells including the DU/2 M ZnSO4 electrolyte were also more pronounced than those with the bare ZnSO4 electrolyte. The maximum corrosion inhibition efficiency of the DU for the zinc electrode in ZnSO4 solution exceeded 82%. Hence, the suppression of zinc corrosion and parasitic side reactions, as well as the formation and growth of zinc dendritic crystals by the addition of DU in zinc sulfate electrolyte, played a central role in intensifying aqueous zinc ion batteries.

Dendrites and side reactions of Zn anodes severely restrict the application of aqueous Zn-based batteries for grid-scale energy storage. While surface/interface modification strategies have shown some progress in improving Zn anode reversibility, they still fall short in addressing the overall regulation and intrinsic mechanisms from the bulk-phase perspective. Herein, a bulk-phase composite Zn/CNTs anodes fabricated by a powder-metallurgy-based strategy is introduced. Benefiting from the regulation of grain boundary engineering on local electric conductivity, electric field distributions, and Zn atom absorption energy, the Zn/CNTs anodes effectively suppress dendrite growth and enhance corrosion resistance during Zn stripping/plating cycles. Symmetrical cells equipped with Zn/CNT4 anodes exhibit extended cycling stability with minimal voltage hysteresis (only 22 mV). Furthermore, the full cells incorporating Zn/CNT4 with commercial MnO 2 demonstrate superior rate performance and specific capacitance retention after 500 h cycling. This breakthrough opens up new avenues for optimizing metallic anodes at the bulk phase level using powder metallurgy, enabling scalable manufacturing processes, and providing valuable insights for various metal anode systems.

Scope The oral absorption, distribution, excretion, and bioavailability of zinc sulfate (ZnS), zinc gluconate (ZnG), and zinc-enriched yeast (ZnY) in rats are fully and systemically compared for the first time. Methods and results After zinc compounds were orally administered to rats at a single dose of 4 mg Zn kg –1 , blood, tissues, urine, and feces at different time points were collected for the quantification of zinc concentration. Blood was also harvested for the zinc assay in the multiple-dose administration. Plasma zinc levels among three zinc compounds showed no difference, and zinc was widely distributed in various tissues with the level sequence of bone > liver > pancreas > testes. The net Zn balance was 2.993, 5.125, and 7.482% for ZnS, ZnG, and ZnY, respectively. Conclusion ZnS, ZnG, and ZnY show equivalent bioavailability based on plasma and tissues zinc levels, although ZnY was statistically more absorbed and retained than ZnS and ZnG based on the excretion amount.

Aqueous zinc (Zn)-based energy storage devices possess promising applications for large-scale energy storage systems due to the advantage of high safety, low price, and environment-friendliness. However, their development is restricted by dendrite growth and hydrogen evolution issues from the Zn-metal anode. Herein, a facile stress-pressing method is reported for constructing a grid zinc anode (GZn) with a conductive framework. The highly conductive copper (Cu)-mesh framework reduces electrode hydrogen evolution and increases electrode conductivity. Meanwhile, the in situ-formed Cu-Zn nano-alloy stabilizes the Zn deposition interface. As a result, the GZn symmetrical cell presents a low overpotential of 49 mV after cycling for 1,200 h (0.2 mA∙cm−2). In addition, GZn displays its potential application as a universal anode for Zn-ion capacitors and batteries. An activated carbon||GZn Zn-ion capacitor delivers a stable cycling performance after 10,000 cycles at 5 A∙g−1 and MnO2||GZn Zn-ion batteries exhibit satisfactory cycle stability and excellent rate performance. This demonstrates that GZn appears to be a promising universal anode for Zn-ion capacitors and batteries.

Zinc metal is a promising choice as a high-capacity and cost-effective anode for aqueous zinc-based batteries. However, it faces challenges related to low cycling stability and poor reversibility due to parasitic reactions and the growth of zinc dendrites. In this study, a solution is proposed by introducing a conductive Ti 4 O 7 layer on the zinc anode to enhance electrode stability. The Ti 4 O 7 layer serves a dual purpose, effectively preventing spontaneous corrosion of the zinc anode in the electrolyte, thereby inhibiting the hydrogen evolution reaction and the generation of byproducts. Simultaneously, it promotes Zn nucleation and ensures a uniform electric field distribution, resulting in homogeneous Zn plating and stripping compared to using a bare zinc anode. Consequently, the Ti 4 O 7 -coated Zn anode experiences a significant reduction in over-potential, demonstrating long-term stability and dendrite-free behavior. This outcome ensures low polarization potential and high cycling stability in zinc-ion batteries. The work underscores the potential of conductive oxides in the development of stable metal electrodes.

Owing to the intrinsically high safety, low cost, natural abundance, and high energy density of Zn metal, aqueous Zn ion batteries (AZIBs) have become a promising candidate for large-scale energy conversion and storage. However, the practical application of AZIBs is hampered by the severe Zn dendrites growth and the poor low-temperature performance due to the elevated freezing point of aqueous electrolyte. Herein, the study proposes a new kind of room-temperature liquid Zn salt, which is called Zn coordinated ionic liquid (i.e., (EMIM) 5 Zn(OTF) 7 ), for all-temperature AZIBs. The aqueous electrolyte containing 0.261 mol kg −1 (EMIM) 5 Zn(OTF) 7 in Ethylene Glycol (EG) / H 2 O (6:4) exhibits ultralow freezing point below −100 °C. The liquid Zn salt and EG molecules not only modulate the solvation structure of Zn 2+ ion, reducing the coordinated H 2 O in the first solvation sheath, but also suppresses the parasitic side reaction. As a proof of concept, Zn || Zn symmetric cells and Zn || PANI full cells with the designed electrolyte achieve improved cycling stability and can operate under wide temperature (from −40 to 60 °C). Even with high Zn utilization ratio of 40%, long cycle life over 70 times with capacity retention of 80% is achieved.

Aqueous Zn-ion batteries have gradually become a suitable choice for large-scale energy storage systems owing to their safety and lower cost. However, Zn metal anodes typically suffer from uneven electrodeposition and zinc dendrite formation, which restricts Zn-ion batteries from being used in further applications. To mitigate this problem, a simple and quick chemical surface modification is employed to construct a multifunctional hybrid interface consisting of ZnF 2 and Sn on the surface of the Zn metal anode. ZnF 2 show a low diffusion energy barrier for Zn 2+ , effectively shield the direct corrosive reaction from the aqueous electrolyte , and simultaneously increase the hydrogen evolution potential of the Zn electrode. Furthermore, the Sn particles provide a large number of nucleation sites and charge centers, avoiding the direct growth of dendrites. The interface-modified Zn anode achieve stable cycles of 700 h and 500 h at high current densities of 5 and 10 mA/cm 2 , respectively, while the assembled Zn@ZnF 2 –Sn||V 2 O 5 full battery achieve over 400 stable cycles at 1 A/g. This work uncover the internal mechanism of inhibiting Zn dendrites by the multifunctional interface, providing a means for stabilizing the Zn anode under practical conditions.

The issues of Zn dendrite and severe Zn 2+ transport destabilization in the electrode/electrolyte interface have been the main obstacles to the commercialization of aqueous Zn-based batteries. Here, a disordered zinc silicate (ZSO) artificial solid electrolyte interphase with high Zn 2+ conductivity (9.29 mS·cm −1 ) is proposed to address these dilemmas. The disordered ZSO interphase possesses sufficient tunnels for fast Zn 2+ transport and highly reversible Zn plating/stripping, which can redistribute the Zn 2+ flux and guide uniform Zn deposition to achieve a dendrite-free Zn metal anode. As a proof of concept in zinc-ion batteries, the Zn@ZSO//NH 4 V 4 O 10 battery delivers a capacity of 336.8 mAh·g −1 at 0.2 A·g −1 , with a capacity retention of 90.1% at 5 A·g −1 over 1,000 cycles. As for the Zn@ZSO//I 2 battery, by inhibiting I 3 − diffusion, 97.98% of capacity is retained after shelving for 60 h. This work provides enlightenment into interface designing and iodide diffusion suppression to accelerate the commercialization of high-performance zinc-based batteries.

Aqueous zinc-ion batteries have been impeded by the hydrogen evolution reaction (HER), uncontrolled zinc dendrites, and side reactions on the Zn anode. In this work, a Zn–polyphenol supramolecular network is rationally designed for stabilizing Zn anodes (ZPN@Zn) even at high current density. Theoretical calculations and experiments show that the zinc–polyphenol supramolecular layer effectively inhibits the hydrogen evolution reaction by capturing water molecules through strong hydrogen bonding networks while also facilitating the rapid replenishment of Zn2+ ions at the interface through supramolecular anchoring. Additionally, it results in preferential deposition of Zn on the (002) plane, thereby contributing to nondendritic and highly reversible Zn plating/stripping behaviors even under high rates. Concomitantly, the ZPN@Zn achieves superior stability of nearly 1200 h at a high current density of 20 mA cm–2 and maintains a high CE efficiency of 99.86% after 3000 cycles at 1 mAh cm–2 and 5 mA cm–2. Remarkably, the full cell assembled with ZPN@Zn and NaV3O8 (NVO) endures 25 000 cycles at 20 A g–1, achieving an impressive performance for the realization of dendrite-free Zn anodes by supramolecular modulation.
