Rechargeable aqueous zinc ion batteries have attracted significant attention because of their non-toxicity, high theoretical capacity, and low cost. However, many challenges regarding zinc anodes have hindered the development of zinc ion batteries , such as the growth of zinc dendrites, passivation and hydrogen evolution . In this study, a simple strategy based on porous rutile nano-TiO 2 coating was used to guide uniform deposition of zinc ions to inhibit the formation of zinc dendrite. The TiO 2 coated zinc anode shows excellent electrochemical performance . Therefore, for Zn Zn symmetric cell, the zinc anode protected by TiO 2 coating shows reduced voltage hysteresis (50 mV at 0.4 mA cm −2 ). Moreover, for Zn-MnO 2 full cell, the cell with TiO 2 coating also shows excellent cycling performance. The discharge capacity of Zn-MnO 2 full cell is only 27.69 mAh g −1 after 500 cycles, while discharge capacity of Zn@TiO 2 -MnO 2 full cell is up to 89.14 mAh g −1 . This excellent electrochemical performance may be attributed to improved wettability of TiO 2 coated zinc anode, the uniform deposition of Zn 2+ and reduction of Zn dendrites. Overall, this study provides a simple and beneficial strategy for future development of rechargeable aqueous zinc ion batteries .

Zinc is a widely used anode material for zinc-ion batteries. However, the problems of dendrites and side reactions faced by the metal zinc anode limit its cycle stability and service life. Surface modification is a simple and effective strategy for preparing high-performance anodes. Here, we used a simple method to coat the γ-Al 2 O 3 on surface of metal zinc as an artificial protective layer for the anode/electrolyte. γ-Al 2 O 3 coating can guide the uniform deposition of zinc ions . The coating has good hydrophilicity, which is conducive to accelerate ion transmission. In addition, the importance of controlling the thickness of protective layer on surface of zinc metal anode to obtain good electrochemical performance is emphasized. The appropriate thickness of Al 2 O 3 coating ensures the rapid migration of zinc ions and improves the uniformity of zinc plating/stripping, which is conducive to more uniform zinc nucleation and high-quality deposition. Therefore, the discharge capacity of Zn@Al 2 O 3 -15 full cell at a current density of 0.3 A g −1 is 174.3 mAh g −1 , which is much higher than that of bare zinc cell (71.8 mAh g −1 ). This work has certain reference significance for the development of anode coating strategies in zinc-ion batteries.

Aqueous zinc-ion batteries (AZIBs) suffer from rampant Zn dendrites growth, corrosion and sluggish transport kinetics, all of which have a serious impact on their performance and practical applications. Therefore, porous carbon nanofibers (BTO@PCNFs) loaded with BaTiO 3 nanoparticles (BTO NPs) are constructed as a multifunctional interlayer for stabilizing the Zn anodes. Owing to the synergistic effect of BTO NPs and 3D porous carbon framework, this interlayer can achieve uniform electric field distribution, accelerate Zn 2+ migration, and promote ion flux homogenization, thus leading to uniform Zn deposition. Meanwhile, the BTO@PCNFs interlayer demonstrates excellent anti-corrosion effect, which can effectively prevent the side reactions. Benefiting from the synergistic effect of interlayers, the BTO@PCNFs multifunctional interlayers achieve a comprehensive optimization of the Zn anodes. The BTO@PCNFs-Zn electrode exhibits lower nucleation overpotential (33.5 mV) at 0.5 mA cm −2 . The Zn//Zn symmetrical cell with BTO@PCNFs interlayer exhibits ultra-low overpotential (14 mV) and ultra-long cycle life (5250 h at 0.5 mA cm −2 ). Even at high current density (30 mA cm −2 ), the BTO@PCNFs-Zn electrode can be stably cycled for more than 830 h, achieving an ultra-high cumulative capacity of 12 450 mAh cm −2 . The multifunctional interlayers can provide a reference for the design of high-performance Zn anodes.

Metallic Zn is a promising anode for high-safety, low-cost, and large-scale energy storage systems. However, it is strongly hindered by unstable electrode/electrolyte interface issues, including zinc dendrite, corrosion, passivation, and hydrogen evolution reactions. In this work, an in situ interface protection strategy is established by turning the corrosion/passivation byproducts (zinc hydroxide sulfates, ZHSs) into a stable hybrid protection layer. The hydrolysis of the diglycolamine buffer layer on the zinc anode provides a homogeneous basic electrolyte environment for the generation of small-sized ZHS, thereby leading to the formation of a ZHS-based hybrid layer. Benefiting from this hybrid layer, uniform zinc ion flux and high anticorrosion ability can be achieved. As a result, the decorated symmetric cell presents a long cycling lifespan of over 1500 h at a current density of 1 mA cm–2 and an area capacity of 1 mAh cm–2. It also contributes to the appealing cycling and rate performance of Zn|NH4V4O10 full cells. This work provides insight into regulating and reusing interfacial byproducts for high-performance zinc metal batteries.

In aqueous zinc-ion batteries, Zn dendrites growth, HER and by-product generation on the surface of Zn anode seriously affect the battery performance. To solve the problems, in this paper, a composite separator is prepared by coating the filter paper with halloysite and ZnO. The 3D network built by surface-negative halloysite provides a uniform nanoscale pore structure for the separator, which achieves uniform and efficient Zn 2+ transport. The –OH groups on the surface of halloysite promote the desolvation process of hydrated Zn 2+ by forming hydrogen bonds with H 2 O. The uniformly dispersed nanoscale ZnO in the coating promotes Zn 2+ transport, homogenizes Zn 2+ deposition on the surface of Zn anode by absorbing Zn 2+ , and reduces the nucleation overpotential (22.3 mV). Therefore, under the synergistic effect of halloysite and ZnO, the electrolyte/Zn anode interface is stabilized. The Zn-symmetric cell assembled with ZHLFP10 exhibits a long life of more than 1600 h at a current density of 0.2 mA cm −2 , while the Zn‖MnO 2 cell assembled with it exhibits a discharge-specific capacity of 131.0 mA h g −1 and a capacity retention rate of 80.35 % at a current density of 0.5 A g −1 for 1000 cycles.

Aqueous zinc-ion batteries (AZIBs) have become popular for energy storage devices due to their cost-effectiveness, high capacity and environmental friendliness. However, the uncontrolled growth of dendrites and corrosion at the zinc anode have seriously hindered AZIBs’ further development. The construction of protective interface layers is a promising strategy to mitigate and suppress the above problems. Herein, we propose the in situ construction of a protective layer of Sn at the zinc anode by coating a suspension of stannous oxalate, which regulates the zinc nucleation sites and induces the deposition of Zn (002) crystal planes, inhibiting the uncontrolled growth of zinc dendrites. The hydrophobic Sn metal protective layer isolated the contact between the active water and the zinc anode and suppressed the corrosion of the zinc anode. As a result, the modified Zn//Zn symmetric cell has a cycle life of 2300 h at 1 mA cm−2, with a significant reduction in the polarisation overpotential. The MnO2//Zn full cell assembled with the modified Zn anode also showed good performance with a specific capacity of 94.74 mA h g−1 after 1000 cycles. This work exemplifies the potential of metal salts in the development of stable metal electrodes.

Aqueous zinc-ion batteries (AZIBs) are currently highly promising rechargeable batteries offering affordable prices and high reliability. However, the uncontrolled expansion of zinc dendrites, hydrogen evolution reaction, and adverse reaction greatly affect their potential sustainable application. Herein, Cu–Sn nanoparticle alloy-modified carbon nanofibers (Cu/Sn–C) are constructed as a buffer interface region onto the zinc anode. The high density of zincophilic sites of the Cu/Sn–C contributes a homogeneous Zn deposition behavior, ameliorates potential separator penetration of zinc dendrites, and weakens corrosions and adverse reactions. As a result, Cu/Sn–C exhibits a low zinc nucleation overpotential of 33.2 mV and dendrite-free zinc deposition. Besides, a symmetric cell with Cu/Sn–C@Zn anode exhibits outstanding cycling lifespan with over 3500 h at 1 mA cm −2 for 1 mAh cm −2 . Furthermore, Cu/Sn–C@Zn//Mn x V 2 O 5 full battery also achieves stable cycling at 5 A g −1 . This work provides a significant avenue for enhancing the reliability of the Zn anode, thereby facilitating the advancement of widespread applications for the next-generation AZIBs. Graphical Cu–Sn nanoparticle alloy-modified carbon nanofibers (Cu/Sn–C) are constructed as a buffer interface region onto the Zn metal anode. The abundant zincophilic sites of the Cu/Sn–C contribute a homogeneous Zn deposition behavior and weaken side reactions. Therefore, Cu/Sn–C presents a superior rate capability and long-term cycling stability.

The Zn dendrite limits the practical application of aqueous zinc-ion batteries in the large-scale energy storage systems. To suppress the growth of Zn dendrites, a zinc ionophore of hydroxychloroquine (defined as HCQ) applied in vivo treatment is investigated as the electrolyte additive. HCQ dynamically regulates zinc ion concentration in the outer Helmholtz layer, promoting even Zn plating at the anode/electrolyte interface . This is evidenced by the scanning electron microscopy, which delivers planar Zn plating after cycling. It is further supported by the X-ray diffraction spectroscopy, which reveals the growth of Zn (0 0 2) plane. Additionally, the reduced production of H 2 during Zn plating/stripping is detected by the in-situ differential electrochemical mass spectrometry (DEMS), which shows the resistance of Zn (0 0 2) to hydrogen evolution reaction. The mechanism of dynamic regulation for zinc ion concentration is demonstrated by the in-situ optical microscopy. The hydrated zinc ion can be further plated more rapidly to the uneven location than the case in other regions, which is resulted from the dynamic regulation for zinc ion concentration. Therefore, the uniform Zn plating is formed. A cycling life of 1100 h is exhibited in the Zn||Zn symmetric cell at 1.6 mA cm −2 with the capacity of 1.6 mAh cm −2 . The Zn||Cu battery exhibits a cycling life of 200 cycles at 4 mA cm −2 with a capacity of 4 mAh cm −2 and the average Coulombic efficiency is larger than 99 %. The Zn||VO 2 battery with HCQ modified electrolyte can operate for 1500 cycles at 4 A g −1 with a capacity retention of 90 %. This strategy in the present work is wished to advance the development of zinc-ion batteries for practical application.

Zinc-ion batteries (ZIBs) are inexpensive and safe, but side reactions on the Zn anode and Zn dendrite growth hinder their practical applications. In this study, 1,3,5-triformylphloroglycerol (Tp) and various diamine monomers ( p -phenylenediamine (Pa), benzidine (BD), and 4,4′’-diamino- p -terphenyl (DATP)) were used to synthesize a series of two-dimensional covalent-organic frameworks (COFs). The resulting COFs were named TpPa, TpBD, and TpDATP, respectively, and they showed uniform zincophilic sites, different pore sizes, and high Young’s moduli on the Zn anode. Among them, TpPa and TpBD showed lower surface work functions and higher ion transfer numbers, which were conducive to uniform galvanizing/stripping zinc and inhibited dendrite growth. Theoretical calculations showed that TpPa and TpBD had wider negative potential region and greater adsorption capacity for Zn 2+ than TpDATP, providing more electron donor sites to coordinate with Zn 2+ . Symmetric cells protected by TpPa and TpBD stably cycled for more than 2300 h, whereas TpDATP@Zn and the bare zinc symmetric cells failed after around 150 and 200 h. The full cells containing TpPa and TpBD modification layers also showed excellent cycling capacity at 1 A/g. This study provides comprehensive insights into the construction of highly reversible Zn anodes via COF modification layers for advanced rechargeable ZIBs.

Aqueous zinc-ion batteries (AZIBs) are considered to be one of the alternatives for large-scale energy storage devices due to unique advantages. However, the harmful Zn dendrites generation of Zn anodes seriously hinders the development of AZIBs. Herein, Cu 3 (BTC) 2 (HKUST-1) as a compact functional interface layer on the surface of bare Zn foil is shown to improve the reversibility of Zn-plating/stripping process. Interestingly, HKUST-1 possesses high porosity, large number of water molecule vacancies, and Cu active center, which help to enhance the diffusion kinetics of Zn 2+ and reduce the surface free energy of Zn electrode. Combining theoretical calculations with experiments, the HKUST-1 can contribute to the desolvation process of Zn[(H 2 O) 6 ] 2+ and balance Zn 2+ concentration, which thus accelerate Zn 2+ transfer kinetics, lower interfacial energy, and homogenize ion-distribution. Attributed to these superiorities, the HKUST-1@Zn symmetric cells demonstrate excellent stable plating/stripping for over 250 h under ultra-high current density (20 mA/cm 2 and 20 mAh/cm 2 ). Furthermore, a HKUST-1@Zn||MnO 2 full cell exhibits an enhanced long-cycling performance with a discharge capacity of 114 mAh/g after undergoing 500 cycles. All results demonstrate the potential application of HKUST-1 coating in AZIBs.

A new route for selective recovery of zinc from hazardous zinc plant purification residue was proposed by alkaline leaching process. The thermodynamic analysis revealed that by controlling solution pH in the range from 14.30 to 16.78 at 25 °C, basic zinc sulfate can be converted to ZnO 2 2− instead of Zn(OH) 2 , while Cd will enter into alkaline leaching residue as a hydroxide. It is feasible to leach selectively Zn and to separate it with Cd by alkaline leaching, and the experimental results confirm that. Under the conditions of NaOH concentration of 3 mol/L, L/S of 20 ml/g, temperature of 40 °C, and time of 50 min, LR of Zn reached 96.14% while them of Pb and Cd were only 0.66% and 2.83% respectively. ZnO with hexagonal wurtzite structure and Cd(OH) 2 were the main phases of leaching residue. They crystallized and adhered to the surface of leaching residue particles, which result in the loose and random particle morphology. The findings confirm that alkaline leaching is efficient in separation of Zn and Cd in ZPPR. In addition, nano-ZnO with flowerlike was synthesized with the zinc-rich leaching solution by precipitation method and the its photocatalytic property was similar to that of nano-ZnO purchased.

BACKGROUD Zinc (Zn) is an essential catalytic element in the human health system but its absorption in the intestinal system can be strongly affected by gastrointestinal (GI) digestion. In this study, the food-derived potential Zn carrier, scallop adductor hydrolysates (SAHs), was produced and characterized. RESULTS During temporary storage at 4 °C, SAH decreased in Zn-chelating capacity in the aqueous phase, whereas the SAH–Zn complex exhibited high stability. Moreover, the secondary structure of SAH had no significant alteration. Zn morphologically altered the surface structures of SAH, which was involving in carboxyl group of SAH. Results of in vitro GI digestion suggested that the SAH–Zn maintained good stability in GI system and only proportion of high molecular weight cleaved. In addition, SAH could successfully carry and transport Zn while the fluorescence staining revealed free Zn accumulation inside the tissue. Finally, three representative absorbed peptides (around 600 Da) were identified and synthesized. Three synthetic peptides exhibit higher Zn-chelating capacity than SAH and could also successfully transported through the intestine. CONCLUSION This study provided a theoretical basis for the investigation of digestion and absorption of marine animal-derived peptides as Zn carriers. © 2021 Society of Chemical Industry.
