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.

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

Interfacial engineering offers a promising solution to zinc anode instability, yet most studies focus solely on suppressing side reactions with water, overlooking the critical role of fast zinc ion kinetics. This work investigates the Cr 2 O 3- x artificial interface layer, demonstrating its dual benefits of electrostatic shielding and enhanced Zn 2+ transport kinetics. The Cr 2 O 3- x layer exhibits excellent mechanical stability and hydrophilicity, with its negatively charged surface effectively repelling anions like SO 4 2− and OH − to suppress side reactions. Moreover, the highly active Cr 2 O 3- x layer accelerates Zn 2+ migration, reduces nucleation energy barriers, and promotes uniform zinc deposition by facilitating Zn 2+ detachment from solvated structures. As a result, the Cr 2 O 3- x @Zn anode achieves exceptional cycling stability and remarkable reversibility, with symmetric batteries enduring over 1,800 h at 5 mA cm −2 . When paired with NH 4 V 4 O 10 , it also demonstrates long cycle life and superior rate performance. This work sheds new light on the development of stable, high-performance zinc anodes.

The unsatisfactory cycling stability of Zn anode stemming from dendritic growth and side reactions has slowed the rapid development of aqueous Zn-ion batteries (AZIBs). Constructing a three-dimensional (3D) artificial interphase layer is an appealing solution since it could dictate Zn deposition at the interface. Here, the in situ growth of a Cu-based metal–organic framework (Cu-MOF) over commercial Zn foil followed by subsequent selenization endows selenized Cu-MOF (SCM) with a stabilized Zn anode. The 3D SCM coating could homogenize the electric field and function as a reservoir to tolerate the deposited Zn. As a result, both rampant dendritic propagation and the notorious side reactions are concurrently inhibited. The SCM@Zn symmetric cell displays an elongated cyclic life for over 500 h at 2.0 mA cm–2. The assembled AZIB full cell readily realizes high electrochemical reversibility under different current densities. Our investigation offers insights into the design of a protective layer for high-performance Zn anodes.

Zn metal is thermodynamically unstable in aqueous electrolytes, which induces dendrite growth and ongoing parasitic reactions at the interface during the plating process and even during shelf time, resulting in rapid battery failure and hindering the practical application of aqueous Zn ion batteries. In this work, glycine, a common multifunctional additive, is utilized to modulate the solvation shell structure and enhance the interfacial stability to guard the reversibility and stability of the Zn anode. Apart from partially replacing the original SO42– in the contact ion pair of Zn2+[H2O]5·OSO32– complexes to suppress the formation of Zn4(OH)6SO4·xH2O byproducts at the interface, glycine molecules can also form a water-poor electrical double layer on the zinc metal surface during resting and be further reduced to build in situ a ZnS-rich solid electrolyte interphase (SEI) layer during cycling, which further suppresses side reactions and the random growth of Zn dendrites in the whole process. As expected, the cycle life of the symmetrical cells reaches over 3200 h in glycine-containing electrolytes. In addition, the Zn//NVO full cell shows exceptional cycling stability for 3000 cycles at 5 A g–1. Given the low-cost superiority of glycine, the proposed strategy for interfacial chemistry modulation shows considerable potential in promoting the commercialization progress of aqueous batteries.

Zn(002) has been proven as a dendrite-free anode for Zn batteries. However, stable Zn plating/stripping behavior at an areal capacity exceeding 5 mAh cm −2 has remained unfulfilled so far. In this study, we show that the planar deposit on pure Zn (002) substrate is loosely stacked with high corrosion tendency by the aqueous electrolyte, the key obstacle to achieving considerable efficiency under high-capacity working conditions. To mitigate the side reactions, we introduce an alloying approach by combining monocrystalline Zn(002) with eutectic Al and Cu. The alloying strategy enhances the electrostatic interaction between deposits and substrate, favoring a dense-packed deposition morphology with improved corrosion resistant ability. Solid solution property of Al and Cu in Zn matrix also ensures the structure stability during repeated plating/stripping cycles. As a result, significant extension in cycle life of Zn alloy (002)-based symmetric cells even under 50 mA cm −2 and 25 mAh cm −2 and performance with high utilization also achieves a leading level without extra methods on surface protection. The modified Zn alloy (002) anode induces high anode utilization, paving the way for Zn batteries to meet the requirements of practical applications.

The development of promising zinc anodes mainly suffers from their low plating/stripping coulombic efficiencies when using aqueous electrolyte, which are mainly associated with the interfacial formation of irreversible by-products. It is urgent to develop technologies that can solve this issue fundamentally. Herein, we report an artificial Sc 2 O 3 protective film to construct a new class of interface for Zn anode. The density functional theory simulation and experimental results have proven that the interfacial side reaction was inhibited via a stratified adsorption effect between this artificial layer and Zn anode. Benefiting from this novel structure, the Sc 2 O 3 -coated Zn anode can run for more than 100 cycles without short circuit and exhibit low voltage hysteresis, and the coulombic efficiency increases by 1.2%. Importantly, it shows a good application prospect when matched with two of popular manganese-based and vanadium-based cathodes. The excellent electrochemical performance of the Sc 2 O 3 -coated Zn anode highlights the importance of rational design of anode materials and demonstrates a good way for developing high-performance Zn anodes with long lifespan and high efficiency.

The electrochemical reduction of carbon dioxide (CO 2 ) is investigated in acetonitrile with tetrabutylammonium perchlorate as an electrolyte using a lead cathode and a sacrificial zinc anode, and the product under such a setup is insoluble zinc oxalate at potentials between −2.2 and −2.8 V vs. Ag rod electrode. Preelectrolysis is an effective method to remove the water in the electrolyte, which makes a distinct reduction peak of CO 2 appear at −2.6 V vs. Ag on cyclic voltammogram. Even trace amounts of water in the electrolyte can interfere with the faradaic efficiency of reduction of CO 2 to oxalate, and the product could be β-ZnC 2 O 4 (in anhydrous solution) or ZnC 2 O 4 · 2H 2 O (if water exists). The faradaic efficiency for oxalate production also depends on the cathode potential and the temperature, and the maximum is 96.8 % at −2.6 V vs. Ag and 5 °C. This is the highest value of CO 2 electrochemical reduction found in the literature under ambient pressure.

For practical rechargeable aqueous zinc-ion batteries, the long-term cycling stability of the zinc anode remains significantly constrained by its low utilization efficiency and the persistent challenge of hydrogen evolution . This study demonstrates the fabrication of ultrathin zinc electrodes with a robust Zn (002) texture while ensuring an adequate supply of zinc metal for use as an anode material . This approach effectively suppresses the tendency of zinc atoms to undergo deposition transformation due to dislocation-induced phenomena. Compared to zinc foils with higher deposition amount, the ultrathin Zn anode exhibits enhanced resistance to dendrite growth and interfacial side reactions. Assembled symmetrical cells based on this ultra-thin Zn anode show a cycle life of 1750 h (1 mAcm −2 , 0.5 mAhcm − 2 ), maintaining stable cycling for over 100h even at a high depth of discharge (DOD) of 46.23%. Additionally, the full cell couple with V 10 O 24 exhibits a high initial capacity of 429.6 mAh g −1 and a capacity retention of 75.8% after 1000 cycles.

In this work, Zn anode with a high compatibility to seawater system is fabricated on stainless steel mesh using an ultra-simple in-system synthesis technique. Physical characterizations reveal that the film electrode is composed by cross-linked Zn nanoflakes structure with outstanding adhesion and mechanical deformation tolerance. Being adopted as seawater-compatible anode, the as-synthesized Zn electrode exhibits a high reversible capacity of 30 mAh cm −2 with obvious advantages such as outstanding rate capability, strong tolerance to real-time varied current, low capacity decay, and good long-term cycling stability. The assembled Zn-air battery performs a maximum energy density of 285 Wh m −2 and successfully lights up various electronic devices. Furthermore, the self-regulation working mechanism and the growth kinetic of Zn electrode are further investigated using in-situ optical microscopy observations and in-situ electrochemical impedance spectroscopy (EIS) techniques. This work demonstrates a promising feasibility for fabricating highly reversible and low-cost Zn electrode in seawater system aiming to large-scale energy storage.
