Aqueous Zn-ion batteries (ZIBs) have great potential in the field of large-scale energy storage. However, the dendrite formation on Zn anodes hinders the practical applications of ZIBs . Herein, a zincic perfluorinated sulfonic acid membrane (ZPSAM) is prepared as a quasi-solid single-ion conductor. In this membrane, Zn-ions move along with the negatively charged branched chains which possess a limited degree of freedom, forming fast Zn-ion transport channels. Consequently, ZPSAM exhibits high conductivity (~1.17 × 10 −3 S cm −1 ), enabling stable Zn plating and stripping processes at a current density of 2 mA cm −2 over 2000 cycles. In addition, due to the confined anion matrix in the membrane, dendrite formation and side reaction are both effectively suppressed. Finally, by applying the electrolyte in both aqueous super-capacitor and Zn-ion batteries, significantly improved cycling performance can be achieved. This work demonstrates a promising solution for the practical use of Zn metal anode in neutral aqueous media , and thus benefits the development of low-cost, high-performance aqueous energy storage devices.

Inheriting the energy storage mechanism of supercapacitors and rechargeable ion batteries, zinc ion capacitors (ZICs) greatly increase their energy density at high power without sacrificing their life span. However, sluggish kinetics and insufficient active sites for Zn2+ storage induced by the significant mismatch of charge carriers with limited pore size hinder the efficient Zn2+ storage and smooth application of carbonaceous cathode materials. Herein, a three-dimensional honeycomb-like porous carbon network (HPCN) was fabricated, which can reduce the diffusion barrier for fast kinetics, produce a high-density defect area, effectively increase active sites for charge storage, and generate a high nitrogen-doping content. Benefiting from these advantages, the optimized ZICs bring out a marvelous energy/power density (130 W h kg−1/11.7 kW kg−1) with an ultrahigh reliable cyclability of 97.8% after 50 000 cycles at a high current density of 5 A g−1. Importantly, systematic ex situ characterizations combined with theoretical calculations demonstrate that the outstanding Zn2+ storage capacity is attributed to the synergistic effect of physical co-adsorption of cations and reversible chemisorption. This work presents an attractive strategy for developing advanced carbon cathodes with suitable pores and accelerates the exploration of charge storage mechanisms, which may open a new avenue for practical supercapacitors.

The main issues encountered in aqueous zinc-ion batteries (ZIBs) include corrosion and passivation of the zinc anode , electrolyte decomposition leading to hydrogen evolution , and dissolution consumption of cathode materials . This study proposes the use of ammonium persulfate (APS) as an electrolyte additive to enhance battery performance. The addition of APS not only adjusts the solvation structure of Zn 2+ , reduces water activity, but also allows NH 4+ ions to preferentially adsorb onto the surface of the zinc electrode, forming a protective layer and achieving dendrite-free zinc anodes. Results indicate that the inclusion of APS additive in the electrolyte can increase the specific capacity of zinc-ion batteries from 321 mAh g −1 to 418 mAh g −1 . Additionally, batteries with APS exhibit superior stability. Under low current density , the battery lifespan can reach 2100 h and a coulombic efficiency can up to 99.6%. This study delves into the design of multifunctional electrolyte additives and provides valuable insights for the development of practical ZIBs.

The development of a low-cost, high-capacity, and insertion-type anode is key for promoting “rocking chair” zinc-ion batteries. Herein, commercial Bi 2 O 3 (BiO) particles are transformed into Bi 2 O 2 Se@Bi 4 O 8 Se (BiOSe) nanosheets through a simple selenylation process. The change in morphology from commercial BiO particle to BiOSe nanosheet leads to an increased specific surface area of the material. The enhanced electronic/ionic conductivity results in its excellent electrochemical kinetics. Ex situ XRD and XPS tests prove the intercalation-type mechanism of BiO and BiOSe as well as the superior electrochemical reversibility of BiOSe compared to BiO. Furthermore, the H + /Zn 2+ co-insertion mechanism of BiOSe is revealed. This makes BiOSe to have low discharge plateaus of 0.38/0.68 V, a high reversible capacity of 182 mA h g −1 at 0.1 A g −1 , and a long cyclic life of 500 cycles at 1 A g −1 . Besides, the BiOSe//MnO 2 “rocking chair” zinc-ion battery offers a high capacity of ≈90 mA h g −1 at 0.2 A g −1 . This work provides a reference for turning commercial material into high-performance anode for “rocking chair” zinc-ion batteries.

Aqueous zinc-iodine batteries (AZIBs) are considered a very promising way to store energy. However, inherent issues such as cathodic slow I₂/I⁻ redox kinetics and anodic zinc (Zn) dendrite growth, limit the practical application of AZIBs. Here, we used just a trace amount of the electrolyte additive cesium iodide (CsI) for homogeneous deposition of Zn 2+ and enhanced cathode kinetics in AZIBs. The introduction of Cs + produces electrostatic shielding layers that regulate the homogenization of Zn 2+ deposition. Besides, I - promotes cathodic kinetics to achieve the effect of increasing the battery capacity. Electrochemical tests show that by adding 5 mM trace CsI to the Zn-Zn symmetric cell, the cycling time was increased to 650 h, and the Zn-Cu half-cell's cycling time was increased to 3000 cycles under conditions of 5 mA cm −2 . More importantly, Zn-I 2 cells can stably cycle for 10000 cycles at 1 A g −1 and 10 A g −1 . The average capacity increased to 97.54 mAh g −1 after 100 cycles at 1 A g −1 and 74.57 mAh g −1 after 100 cycles at 10 A g −1 . After 100 cycles, the Zn-I 2 full cell's capacity retention rose from 2.41 % to 57.47 % under the conditions of 1 A g −1 and a 5.6 N/P ratio.

Liquid metal battery (LMB) has raised extensive interest in the field of large-scale energy storage applications . The Zn-based LMB composed of inexpensive Zn and low-temperature electrolyte have proven to be feasible and promising. However, the low voltage plateau and coulombic efficiency still limit their practical application. Here we demonstrate a simple design Zn-based LMB, which consists of Zn 5 Sn 5 alloy as negative electrode , Bi as positive electrode and ZnCl 2 –LiCl–KCl molten salt with lower zinc chloride content as electrolyte. The battery can stably operate at a low temperature of 375 °C and exhibit a flat and high voltage plateau of 0.8–0.9 V. A high coulombic efficiency of over 96% can be achieved by optimizing the composition of electrolyte. Sn is added to yield a liquid negative electrode, and then the problem of Zn dendrites can be avoided. In addition to Zn, both Sn and Bi participate in the redox reaction , which contributes to a multiple redox reaction mechanism. The Zn-based liquid metal batteries with low temperature and high voltage will be a prospective choice for large-scale energy storage.

Zinc–iodine (Zn/I2) batteries are recognized as a kind of leading candidate for large-scale energy storage systems, owing to the high-capacity dissolution–deposition reactions on both electrodes. Nevertheless, the lifespan of Zn/I2 batteries is severely limited by the uncontrolled shuttling of triiodide ions (I3–) and unfavorable side reactions on Zn anodes. Herein, an alginate-based polyanionic hydrogel electrolyte is designed and synthesized by ion exchange and Zn2+-induced cross-linking. The immobile, negatively charged polyanionic chains on the hydrogel skeleton effectively block I3– from shuttling, while simultaneously transporting cations that are indispensable for battery chemistry. Moreover, this hydrogel can also enhance the cycling durability of Zn anodes by alleviating Zn’s dendritic growth and corrosion reactions, due to the homogenized Zn2+ flux and reduced interfacial contact between free water and metallic Zn. Consequently, this alginate-based hydrogel electrolyte enables stable Zn plating/stripping for over 600 h at 2 mA cm–2 and 2 mAh cm–2 (corresponding to 10% depth of discharge). Serving as an electrolyte for Zn/I2 full batteries, this hydrogel helps the battery to achieve a high capacity of 183.4 mAh g–1 (capacity retention = 97.6%) after even 200 cycles at 0.2 A g–1, 77.4% higher than that of the traditional ZnSO4 aqueous counterpart (residual capacity = 41.5 mAh g–1). This work indicates the promising potential of electrolyte design on the performance improvement of aqueous Zn/I2 batteries.

One of the hottest research topics at present is the construction of environmentally friendly and secure aqueous zinc-ion batteries (AZIBs) using an aqueous electrolyte instead of an organic electrolyte. As a result of their diverse structure, valence state, high theoretical specific capacity, and other benefits, vanadium-based materials, which are frequently employed as the cathode of AZIBs, have drawn the attention of many researchers. The low cycle stability of zinc ion batteries (ZIBs) is mostly caused by the disintegration of the vanadium-based cathode materials during continuous charge and discharge. In this work, using 3M Zn(CF3SO3)2as the electrolyte and hydrothermally synthesized Ag2V4O11as the cathode material, the high-rate performance and extended cycle life of ZIBs were evaluated. The effects of different hydrothermal temperatures on the microstructure, capacity, and cycle stability of the Ag2V4O11cathode material were examined. The experimental results show that Ag2V4O11exhibits a typical intercalation-displacement process when used as the cathode material. The multiplicative performance and cycle stability of the cathode material were significantly enhanced at a hydrothermal temperature of 180 °C. Ag2V4O11-180 has a high discharge specific capacity of 251.5 mAh·g−1at a current density of 0.5 A·g−1and a long cycle life (117.6 mAh·g−1after 1000 cycles at a current density of 3 A·g−1). According to the electrochemical kinetic investigation, the cathode material has a high pseudocapacitive charge storage and Zn2+diffusion coefficient. This is attributed to the large layer spacing and the Ag+anchored interlayer structure.

Cadmium (Cd), a prevalent pollutant in near-shore seawater ecosystems, poses a significant threat to marine biota. Zinc (Zn) and Cd can have interchangeable physiological effects in marine plankton, and both can influence the synthesis of siliceous walls. Consequently, the concentrations of zinc and silicon may jointly impact the toxicity of Cd. This study endeavors to elucidate the combined effect of silicon (Si) and zinc (Zn) on the growth and physiological responses of the marine diatom species Thalassiosira weissflogii when subjected to Cd-induced stress conditions (190.7 μg L −1 ). Our results reveal statistically improvements ( p <0.05) in biomass production, reductions ( p <0.05) in superoxide dismutase (SOD) activity and extracellular secretion in T. weissflogii when high concentrations of Si (172 µmol L −1 ) and Zn (18.3 nmol L −1 ) were applied simultaneously. Additionally, examination of Cd bioconcentration factors (BCF) derived from Cd uptake kinetics and intracellular Cd content measurements underscores the ability of elevated Si and Zn concentrations to reduce intracellular Cd accumulation ( p <0.05). The ability of Si and Zn to mitigate Cd toxicity was further evidenced by increased cellular biosilica content and maintenance of cell morphology, suggesting a protective role in preserving structural integrity and growth. Our findings underscore the synergistic benefits of Si and Zn in enhancing the resilience of T. weissflogii to Cd stress, providing valuable insights into the potential use of nutrient amendments as a strategy for mitigating heavy metal contamination in marine environments.

Because of their low cost, safety, and green nature, aqueous Zn-ion batteries are promising candidates for energy storage. However, the appearance of Zn dendrites, hydrogen evolution reaction (HER), and corrosion limit the development of the aqueous Zn-ion batteries. Here, inspired by fibrous cartilage, a biomimetic poly(vinylidene fluoride) (PVDF)-based composite polymer coating layer, including aramid nanofiber (ANF) and zinc trifluoromethanesulfonate [Zn(CF3SO3)2], called ANFZ, was designed and fabricated. The high ionic conductivity (3.84 mS cm–1) of the flexible PVDF matrix, optimized by Zn(CF3SO3)2, combined with the highly mechanical ANF network can effectively guide the rate of Zn stripping/plating, homogenize the Zn2+ distribution, and suppress the dendrites. In addition, the high Coulombic efficiency is obtained due to the suppression of HER and corrosion by the biomimetic coating layer. Symmetric ANFZ@Zn//ANFZ@Zn can steadily work over 1000 h at 1 mA cm–2 with a high degree of reversibility, which is greater than that of bare Zn//bare Zn. Furthermore, the ANFZ@Zn//MVO batteries show a high specific capacity (400.2 mAh g–1, 0.1 A g–1) and a long cycle life. This work presents a novel method combined with bionics for designing and assembling Zn anodes without dendrites for zinc-ion batteries.

Aqueous zinc-ion batteries (AZIBs) have attracted extensive attention because of their eco-friendliness, intrinsic safety, and high theoretical capacity. Nevertheless, the long-standing Zn anode issues such as dendrite growth, hydrogen evolution, and passivation greatly restrict the further development of AZIBs. Herein, a metal–chelate interphase with high Zn affinity is constructed on the Zn metal surface (TA@Zn) via dipping metallic Zn into a tannic acid (TA) solution to address the aforementioned problems. Benefiting from the abundant hydrophilic and zincophilic phenolic hydroxyl groups of TA molecules, the metal–chelate interphase shows strong attraction for Zn2+ ions, guiding uniform zinc deposition as well as decreasing Zn2+ migration barrier. Therefore, the TA@Zn anode displays an extended lifespan of 850 h at 1 mA cm−2, 1 mAh cm−2 in the Zn|Zn symmetrical cell, and a high Coulombic efficiency of 96.8% in the Zn|Ti asymmetric cell. Furthermore, the Zn|V2O5 full cell using TA@Zn anode delivers an extremely high capacity retention of 95.9% after 750 cycles at 2 A g−1. This simple and effective strategy broadens the interfacial modification scope on Zn metal anodes for advanced rechargeable Zn metal batteries.

The rational design of nanoscale metal oxides with hollow structures and tunable porosity has stimulated tremendous attention due to their vital importance for practical applications. Here, we report the designed synthesis of ZnO/ZnCo2O4 hollow core–shell nanocages (HCSNCs) through a metal–organic framework (MOF) route. The strategy includes the synthesis of a zeolite imidazolate framework-8 (ZIF-8)/Co–Zn hydroxide core–shell nanostructure precursor and subsequent transformation to ZnO/ZnCo2O4 HCSNCs by thermal annealing of the as-prepared precursor in air. Various techniques were employed for characterization of the structure and morphology of the as-prepared ZnO/ZnCo2O4 HCSNCs. When applied as a gas sensing material, the ZnO/ZnCo2O4 HCSNCs show enhanced sensitivity to xylene when compared with ZnCo2O4 shells as well as ZnO nanocages (NCs). In addition, excellent reversibility and superior selectivity of the sensor were observed. The remarkable enhancement in the gas-sensing properties of the ZnO/ZnCo2O4 HCSNCs is attributed to their unique structure and a synergistic effect of ZnO and ZnCo2O4.
