Rechargeable aqueous zinc-ion batteries (RAZIBs) are recognized as promising energy storage systems to meet the ever-growing demand for grid-scale applications. Developing reliable cathode materials with superior electrochemical performance plays a decisive role in this field. In this work, an electrochemical oxidation strategy is employed to successfully activate the electrochemical activity of ZnV 2 O 4 spinel oxide. Operating at high potentials up to 2.0 V enables the capacity activation process efficiently, in which the specific capacity increases from 86 to 232 mAh g −1 (corresponding to 170% capacity enhancement) after 50 cycles at 2 A g −1 . On the contrary, ZnV 2 O 4 operating in the potential window of 0.4−1.6 V only delivers 87 mAh g −1 after 50 cycles, whereas negligible capacity (<3 mAh g −1 ) is obtained in the case of 0.4−1.3 V. As characterized by X-ray diffraction (XRD), Raman microscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and in situ pH measurements, the underlying mechanism is unraveled as a hydrolysis reaction coupled with the dissolution−recrystallization process, leading to the formation of high-valent Zn 0.06 V 2 O 5 •1.07H 2 O with a localized layered structure. The activated cathode demonstrates facilitated ion transport kinetics, reduced charge transfer resistance, and high electrochemical reversibility in RAZIBs. Benefiting from these features, stable cycle stability is achieved, that is, a reversible capacity of 138 mAh g −1 (83% capacity retention) can be retained after 2000 cycles at 4 A g −1 . This work sheds light on activating low-valent vanadium-based oxides for practical application in RAZIBs, opening an avenue for developing cathode materials for aqueous batteries.

“…[ 6 ] The charge/discharge curve of N v ‐VN/C‐SS‐2 is shown in Figure 3c , the significant charging and discharging platforms are positioned at ≈1.12 and 0.65 V, respectively, which is consistent with the CV test result. As a result, a high discharge specific capacity of 257 mAh g −1 can be achieved (50 cycles, 0.2 A g −1 ) (Figure 3d ), which is higher than most of the currently reported AZIBs [ 10 , 14 , 17 , 18 , 19 , 38 , 39 , 40 , 41 , 42 ] (Table S1 , Supporting Information). In contrast, N v ‐VN/C‐SS‐1, and N v ‐VN/C‐SS‐3 exhibit poor specific capacity, the specific capacities are 180 and 108 mAh g −1 , respectively.…”

Vanadium nitride (VN) is a potential cathode material with high capacity and high energy density for aqueous zinc batteries (AZIBs). However, the slow kinetics resulting from the strong electrostatic interaction of the electrode materials with zinc ions is a major challenge for fast storage. Here, VN clusters with nitrogen‐vacancy embedded in carbon (C) (Nv‐VN/C‐SS‐2) are prepared for the first time to improve the slow reaction kinetics. The nitrogen vacancies can effectively accelerate the reaction kinetics, reduce the electrochemical polarization, and improve the performance. The density functional theory (DFT) calculations also prove that the rapid adsorption and desorption of zinc ions on Nv‐VN/C‐SS‐2 can release more electrons to the delocalized electron cloud of the material, thus adding more active sites. The Nv‐VN/C‐SS‐2 exhibits a specific capacity and outstanding cycle life. Meanwhile, the quasi‐solid‐state battery exhibits a high capacity of 186.5 mAh g−1, ultra‐high energy density of 278.9 Wh kg−1, and a high power density of 2375.1 W kg−1 at 2.5 A g−1, showing excellent electrochemical performance. This work provides a meaningful reference value for improving the comprehensive electrochemical performance of VN through interface engineering.

“…As the scanning rate increases, the CV curves retained similar shapes. Compared to those of the V 10 cathode (Figure S12), the current responses of TPA-V 10 are higher at the same scan rate, indicating better energy storage capability in the TPA-V 10 cathode . The electrochemical dynamic process can be analyzed by the power law relationship between scanning rate ν and peak current i in CV curves: i = a ν b, where a and b are adjustable parameters, with b = 0.5 representing a diffusion control process and b = 1 representing a capacitance control process .…”

Aqueous zinc-ion batteries hold promise for sustainable energy storage, yet challenges in finding highperformance cathode materials persist. Polyoxovanadates (POVs) are emerging as potential candidates due to their structural diversity and robust redox activity. Despite their potential, issues like dissolution in electrolytes, structural degradation, and byproduct accumulation persist. This work introduces a POVbased hydrophobic two-dimensional (2D) layered superstructure that addresses these challenges. The hydrophobic nature minimizes POV dissolution, enhancing structural stability and inhibiting phase transitions during cycling. The 2D arrangement ensures a larger surface area and improved electronic conductivity, resulting in faster kinetics and higher specific capacity. The superstructure demonstrates improved cycle life and an increased operating voltage, marking a significant advancement in POV-based cathode materials for aqueous zinc-ion batteries.
