Aqueous zinc ion batteries (AZIBs) are promising electrochemical energy storage devices due to their high theoretical specific capacity, low cost, and environmental friendliness. However, uncontrolled dendrite growth poses a serious threat to the reversibility of Zn plating/stripping, which impacts the stability of batteries. Therefore, controlling the disordered dendrite growth remains a considerable challenge in the development of AZIBs. Herein, a ZIF-8-derived ZnO/C/N composite (ZOCC) interface layer was constructed on the surface of the Zn anode. The homogeneous distribution of zincophilic ZnO and the N element in the ZOCC facilitates directional Zn deposition on the (002) crystal plane. Moreover, the conductive skeleton with a microporous structure accelerates Zn2+transport kinetics, resulting in a reduction in polarization. As a result, the stability and electrochemical properties of AZIBs are improved. Specifically, the ZOCC@Zn symmetric cell sustains over 1150 h at 0.5 mA cm−2with 0.25 mA h cm−2, while the ZOCC@Zn half-cell achieves an outstanding Coulombic efficiency of 99.79% over 2000 cycles. This work provides a simple and effective strategy for improving the lifespan of AZIBs.Keywords:aqueous zinc ion batteries;MOFs;anode;dendrite growth

A two-dimensional MXene (Ta4C3) was innovatively used herein to modulate the space group and electronic properties of vanadium oxides, and the MXene/metal–organic framework (MOF) derivative VO2(B)@Ta4C3 with 3D network cross-linking was prepared, which was then employed as a cathode to improve the performance of aqueous zinc ion batteries (ZIBs). A novel method combining HCl/LiF and hydrothermal treatments was used to etch Ta4AlC3 to obtain a large amount of accordion-like Ta4C3, and the V-MOF was then hydrothermally grown on the surface of the stripped Ta4C3 MXene. During the annealing process of V-MOF@Ta4C3, the addition of Ta4C3 MXene liberates the V-MOF from agglomerative stacking, allowing it to show additional active sites. More significantly, Ta4C3 prevents the V-MOF in the composite structure from converting into V2O5 of space group Pmmn but into VO2(B) of space group C2/m after annealing. A considerable advantage of VO2(B) for Zn2+ intercalation is provided by the negligible structural transformation during the intercalation process and the special tunnel transport channels, which have an enormous area (0.82 nm2 along the b axis). According to first-principles calculations, there is a strong interfacial interaction between VO2(B) and Ta4C3, which deliver remarkable electrochemical activity and kinetic performances for the storage of Zn2+. Therefore, the ZIBs prepared with the VO2(B)@Ta4C3 cathode material exhibit an ultra-high capacity of 437 mA h·g–1 at 0.1 A·g–1 while showing good cycle performance and dynamic performance. This study will offer a fresh approach and a reference for creating metal oxide/MXene composite structures.

Herein, oxygen-deficient NH 4 V 4 O 10 micro-flowers with loaded Ag quantum dots and pre-intercalated Ag + (NVO-Ag) for aqueous zinc ion battery (AZIB) cathode materials were successfully synthesized by a one-step hydrothermal method. The reversible redox reaction between Ag + and Ag quantum dots, and the abundant Zn 2+ storage sites from oxygen vacancies provided capacity contributions for NVO-Ag. Meanwhile, the loaded Ag quantum dots, pre-intercalated Ag + and introduced oxygen vacancies synergistically optimized the electronic structure and distribution of NVO-Ag, promoting the transport of electrons in NVO-Ag. The pre-intercalated Ag + could also replace the NH 4 + in the interlayer of NH 4 V 4 O 10 , weakening the repulsion between the interlayer NH 4 + and Zn 2+ , which achieved rapid Zn 2+ diffusion kinetics. Moreover, the abundant oxygen vacancies in NVO-Ag could alleviate the strong electrostatic interaction between Zn 2+ and V-O framework, boosting the transmission of Zn 2+ in NVO-Ag. Finally, the structural stability of NH 4 V 4 O 10 micro-flowers was improved due to the high bonding strength between Ag + and V-O layers. Benefiting from the above effects, NVO-Ag-100 achieved excellent capacity performance (387.2 mAh g −1 at 0.5 A g −1 ), rate performance (178.9 mAh g −1 at 12 A g −1 ) and cycle stability (91.7 % capacity retention after 1700 cycles at 8 A g −1 ). This work provided effective ideas to achieve high-performance AZIB cathode materials.

Aqueous zinc ion batteries (AZIB) have become a research hotspot for energy storage systems (ESS) in recent years due to some advantages such as their low risk and low cost. However, the structural collapse during charging and discharging affects the reversibility of the battery , which is a very serious blow to manganese-based materials and will affect their subsequent development in batteries. Therefore, β-MnO 2 cathode materials doped by the rare earth element europium (Eu) were prepared by a simple hydrothermal method . Compared with β-MnO 2 , Eu-doped MnO 2 possessed a high specific capacity of 409 mA h g −1 at 0.2 A g −1 . The initial specific capacity of Eu-doped MnO 2 at 1 A g −1 was 200.23 mA h g −1 and the maximum discharge specific capacity of 254 mA h g −1 was reached at 128 cycles. The energy storage mechanism of the electrodes was investigated by ex-situ XRD and ex-situ XPS tests. It was found that Eu element doping to β-MnO 2 not only maintains the stability of the crystal structure during redox reaction, but also promotes the embedding reaction of H + /Zn 2+ . The combination of rare earth elements Eu and MnO 2 is a new direction in the development path of aqueous zinc ion batteries.

As a typical transition-metal dichalcogenides, vanadium diselenide (VSe2) is a promising electrode material for aqueous zinc-ion batteries due to its metallic characteristics and excellent electronic conductivity. In this work, we propose a strategy of hydrothermal reduction synthesis of stainless-steel (SS)-supported VSe2 nanosheets with defect (VSe2–x-SS), thereby further improving the conductivity and activity of VSe2–x-SS. Density functional theory calculations confirmed that Se defect can adjust the adsorption energy of Zn2+ ions. This means that the adsorption/desorption process of Zn2+ ions on VSe2–x-SS is more reversible than that on pure SS-supported VSe2 (VSe2-SS). As a result, the Zn//VSe2–x-SS battery showed more excellent electrochemical performance than Zn//VSe2-SS. The VSe2–x-SS electrode shows a good specific capacity of 265.2 mA h g–1 (0.2 A g–1 after 150 cycles), satisfactory rate performance, and impressive cyclic stability. In addition, we also have explored the energy-storage mechanism of Zn2+ ions in this VSe2–x-SS electrode material. This study provides an effective strategy for the rational design of electrode materials for electrochemical energy-storage devices.

Aqueous zinc ion batteries (AZIBs) have been widely investigated due to their characteristics of convenient operation and intrinsic safety. However, there are several issues to be addressed in AZIBs, such as slow diffusion kinetics of Zn2+, cathode material dissolution and the dendrite formation of zinc anodes. Thus, it is challenging to prepare a high-performance cathode material. In this work, we prepare NH4V4O10 flower-like structures by a facile hydrothermal route. The introduction of chitosan significantly enlarges the layer spacing of the (001) crystal plane. The assembled Zn//NVO-0.15C batteries deliver a specific capacity of 520.54 mA h g−1 at a current density of 0.2 A g−1. Furthermore, they maintain 91% of the retention rate at 5.0 A g−1 after 1000 times cycling. It demonstrates the excellent zinc ion storage behavior of ammonium vanadate electrode materials for AZIBs.

The lack of suitable cathode materials with a high capacity and good stability is a crucial problem affecting the development of aqueous Zn-ion batteries. Herein, a novel strategy for the modification of V2CTx through molten salt thermal treatment is proposed. In the novel route, S heteroatoms were introduced into V2CTx through a substitution reaction during the dissolution of Li2S in LiCl–KCl molten salts. Then, surface V2O5 was obtained through the in situ electrochemical charging/discharging of the S-doped V2CTx (MS-S-V2CTx) cathode. The assembled Zn/MS-S-V2CTx battery showed a high reversible discharge capacity of 411.3 mAh g–1 at a current density of 0.5 A g–1, an 80% capacitance retention after long cycle stability tests at 10 A g–1 for 3000 cycles, and a high energy density of 375.5 Wh kg–1 in 2M ZnSO4. Density functional theory calculations demonstrate that the improved electrochemical performance of the cathode can be attributed to the introduced S heteroatoms, which considerably reduced the ion diffusion energy barrier for Zn2+ ions and improved the stability of V2O5. This work provides a novel method to produce highly active and stable vanadium-based cathodes for aqueous Zn-ion batteries.

Birnessite-type MnO 2 (δ-MnO 2 ) exhibits great potential as a cathode material for aqueous zinc-ion batteries (AZIBs). However, the structural instability and sluggish reaction kinetics restrict its further application. Herein, a unique protons intercalation strategy was utilized to simultaneously modify the interlayer environment and transition metal layers of δ-MnO 2 . The intercalated protons directly form strong O H bonds with the adjacent oxygens, while the increased H 2 O molecules also establish a hydrogen bond network (O H···O) between H 2 O molecules or bond with adjacent oxygens. Based on the Grotthuss mechanism, these bondings ultimately enhance the stability of layered structures and facilitate the rapid diffusion of protons. Moreover, the introduction of protons induces numerous oxygen vacancies , reduces steric hindrance , and accelerates ion transport kinetics. Consequently, the protons intercalated δ-MnO 2 (H-MnO 2-x ) demonstrates exceptional specific capacity of 401.7 mAh/g at 0.1 A/g and a fast-charging performance over 1000 cycles. Density functional theory analysis confirms the improved electronic conductivity and reduced diffusion energy barrier. Most importantly, electrochemical quartz crystal microbalance tests combining with ex-situ characterizations verify the inhibitory effect of the interlayer proton environment on basic zinc sulfate formation. Protons intercalation behavior provides a promising avenue for the development of MnO 2 as well as other cathodes in AZIBs.

Aqueous zinc-ion batteries (ZIBs) with the characteristics of low production costs and good safety have been regarded as ideal candidates for large-scale energy storage applications. However, the nonconductive and non-redox active polymer used as the binder in the traditional preparation of electrodes hinders the exposure of active sites and limits the diffusion of ions, compromising the energy density of the electrode in ZIBs. Herein, we fabricated vanadium pentoxide nanofibers/carbon nanotubes (V2O5/CNTs) hybrid films as binder-free cathodes for ZIBs. High ionic conductivity and electronic conductivity were enabled in the V2O5/CNTs film due to the porous structure of the film and the introduction of carbon nanotubes with high electronic conductivity. As a result, the batteries based on the V2O5/CNTs film exhibited a higher capacity of 390 mAh g−1at 1 A g−1, as compared to batteries based on V2O5(263 mAh g−1). Even at 5 A g−1, the battery based on the V2O5/CNTs film maintained a capacity of 250 mAh g−1after 2000 cycles with a capacity retention of 94%. In addition, the V2O5/CNTs film electrode also showed a high energy/power density (e.g., 67 kW kg−1/267 Wh kg−1). The capacitance response and rapid diffusion coefficient of Zn2+(~10−8cm−2s−1) can explain the excellent rate capability of V2O5/CNTs. The vanadium pentoxide nanofibers/carbon nanotubes hybrid film as binder-free cathodes showed a high capability and a stable cyclability, demonstrating that it is highly promising for large-scale energy storage applications.Keywords:aqueous zinc-ion battery;vanadium pentoxide;carbon nanotubes;hybrid film

Aqueous zinc-ion batteries have attracted attention due to their low cost and high safety. Unfortunately, dendrite growth, hydrogen evolution reactions, cathodic dissolution, and other problems are more serious; not only that, but also the cathodic and anodic materials’ lattices contract when the temperature drops, and charge transfer and solid phase diffusion become slow, seriously aggravating dendrite growth. At present, there are few studies on the low-temperature system, and studies on retaining high specific capacity are even more rare. Herein, ethylene glycol (EG) and manganese sulfate (MSO) are selected as additives, and the manganese vanadate (MVO) cathode is used to find a high-performance solution at low temperature. MVO can provide higher specific capacity and better structural stability than MnO2 to adapt to a low-temperature environment. At the same time, Mn2+ in MSO can produce a cationic shield covering the initial zinc tip at an appropriate concentration to avoid the tip effect and inhibit the dissolution of MVO. EG can not only reduce the freezing point of the electrolyte but also promote the desolvation of [Zn(H2O)6]2+. The synergistic effect of the three elements prevents the dissolution equilibrium of Mn2+ in MVO from fluctuating greatly due to the change of temperature. Therefore, when we use EG@0.2 M MnSO4 + 2 M ZnSO4 (EG + 0.2Mn/2ZSO) electrolyte at −30 °C, the Zn||Zn batteries which used this type of electrolyte can remain 350 h at 1 mA cm–2 without failure. The Zn||Cu batteries can retain 100% Coulombic efficiency after more than 2000 cycles at 0.2 mA cm–2. The Zn||MVO battery can reach 231.13 mA h g–1 at its first cycle, and the capacity retention rate is still above 85% after 1000 cycles, which is higher than that of the existing low-temperature research system.

Aqueous zinc-ions batteries (AZIBs) are expected to be a new green energy storage devices due to the low cost and safety. As classic cathode materials for AZIBs, layered vanadium oxides have excellent redox activity and large capacity performance. However, it not only has poor conductivity, but easily dissolved during (dis)charge process. Therefore, it is necessary to modify vanadium oxide to improve electrochemical performance in AZIBs. Herein, we successfully synthesized V 2 O 3 with carbon shell (V 2 O 3 @C) by the reduction reaction of carbon with V 2 O 5 in an oxygen-free environment and tested its electrochemical performance. By exploiting the effect of different calcination temperatures on the carbon reduction reaction, V 2 O 3 @C nanospheres with different carbon shell thicknesses were successfully synthesized. After fitting the experimental data, the calcination temperature for optimal electrochemical performance was determined to be 800 ℃ (VC-800). Detailly, the capacities of V 2 O 3 @C obtained at 700, 800 and 900 ℃ in the first 100 cycles at 0.5 A/g were 454.5, 400.7 and 325.1 mAh/g, respectively. Furthermore, the obtained VC-800 showed 126 % capacity retention after 10,000 cycles at 10 A/g. In the presence of carbon shell, V 2 O 3 maintains the reversible redox valence characteristics while improving the conductivity and cycle life. This work may broaden ideas in improvement of vanadium-based materials for zinc ion storage.
