Furious dendritic growth and destructive parasitic reactions (hydrogen evolution reaction, corrosion, and passivation) severely degraded the development of aqueous Zn-ion batteries (AZIBs) in the field of grid and stationary energy storage. Herein, trace amount of tetracycline hydrochloride (TC-HCl) additive (only 0.5 mM) is employed as a mediator to steer a stable Zn anode-electrolyte interface. Informed by theoretical calculations and experiment analysis, TC molecule with zincophilic groups can remodel the solvation sheath and disrupt H-bonds network due to its high electronegative O atoms, which effectively expedites the desolvation process and reduces the electrochemical activity of solvent water. Additionally, the TC molecules are preferentially adsorbed on the Zn electrode than active water molecules, which are beneficial for steering uniform nucleation and restricting the erosion of electrode. Benefitting from these synergistic effects, the Zn//Zn symmetric cell containing TC-HCl additive exhibits an ultra-long cycle life of exceeding 2200 h at 1.0 mA cm −2 and 1.0 mAh cm −2 . Accordingly, the practical Zn//α-MnO 2 full cell using the modified electrolyte also demonstrates the enhanced performance. This study provides valuable insights into the widespread use of trace electrolyte additives and facilitates the industrialization of AZIBs with long lifespans.

Aqueous zinc ion batteries (AZIBs) have received widespread consideration owing to non-toxicity, proper capacity, and abundant reserves. Among numerous cathode materials , organics with adjustable structures are prospective campaigners. Naphtha [2, 3-h] naphtha [2', 3': 7, 8] quinoxalino [2, 3-a] naphtha [2', 3': 7, 8] quinoxalino [2, 3-c] phenazine-5, 10, 15, 20, 25, 30-hexaone (AQPH) with large conjugated structure is synthesized through convenient condensation reaction . As an organic cathode of AZIBs, multiple active sites endow AQPH with a decent capacity (297.7 mAh g −1 under 0.05 A g −1 ) and a brilliant cycling life (over 10,000 cycles under 10 A g −1 ). Simultaneously, large conjugated structure supplies AQPH with a rapid electron transfer rate, inducing a high Zn 2+ diffusion coefficient (3.3 × 10 −10 ∼2.6 × 10 −8 cm 2 s −1 ) and an outstanding rate ability (96.7 mAh g −1 under 20 A g −1 ). Furthermore, theoretical calculations and ex-situ characterizations prove that C O and C N are the active sites of Zn 2+ storage. This work demonstrates that expanded conjugated structure and increased active centers of organic molecules are beneficial for accomplishing sustainable high-performance AZIBs.

The exploration of a stable and high-rate cathode is very important for rechargeable Zn ion batteries (ZIBs). With unique merits of rich abundance, low price, and environmental friendliness, spinel ZnMn 2 O 4 (ZMO) hold great promise as a cathode material for ZIBs. However, its inherent low electronic conductivity and large volume variation in the process of charge/discharge severely restrict the rate capability and durability. Herein, the novel N-doping coupled oxygen vacancies modulated ZMO nanotube arrays (NTAs) (N-ZMO NTAs) are fabricated as high-performance cathode for rechargeable ZIBs. Taking advantages of high electrical conductivity, fast ion diffusion, high surface area, sufficient active sites, and stable hollow nanotubular architecture, the N-ZMO NTAs show an admirable capacity (223 mA h g −1 at 0.1 A g −1 ), decent rate capability (133.3 mA h g −1 at 4 A g −1 ) and distinguished long-term durability (92.1% after 1500 cycles). Furthermore, a flexible quasi-solid-state ZIBs is fabricated with N-ZMO NTAs cathode, which achieves favorable energy density (214.6 W h kg −1 ), superb power density (4 kW kg −1 ), and impressive long-term stability (88.6% after 1500 cycles), outperforming most state-of-the-art ZIBs. This study may shed light on designing advanced cathodes for advanced ZIBs.

Hydrogel electrolytes have been widely explored in flexible zinc batteries owing to their considerable mechanical strain and water-retaining properties. However, it is difficult to balance the contradiction between the ionic conductivity and the mechanical strength due to the deterioration of structural stability with the addition of electrolyte salts. To address this, we designed a coassembling organic–inorganic hydrogel (P–P/M) based on poly(vinyl alcohol)-polyacrylamide (P–P) interpenetrating matrix decorated with Zn-based montmorillonite (Zn-MMT). The Zn-MMT with overall negative potential can attract and regulate the transport of Zn2+, while the Brønsted/Lewis acid sites with positive polarizations offer anchoring sites for anions, which increases the cation transference number and reduces byproduct formation. Moreover, the formation of hydrogen bonds in the hydrogel can weaken the contact between free water molecules and the zinc cations, which effectively suppresses the corrosion of zinc foil. Consequently, the Zn//Zn cell with P–P/M electrolyte delivers a long cycle life of 2400 h at 0.5 mA cm–2. The good mechanical properties of the P–P/M hydrogel boost its application in flexible pouch cells even under bending and cutting conditions. This study provides an effective approach to designing organic–inorganic hydrogel electrolytes for long-life flexible zinc batteries.

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.

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.
