world's energy system from non-renewable fossil energy to low-carbon and multienergy fusion. How to fully develop and efficiently utilize clean energy to achieve carbon emission reduction has become a common concern of all countries around the world. In recent years, highly efficient electrochemical energy storage devices have attracted more attention and significantly impacted on scientific and industrial communities. [1] They can execute intermittent power storage and release, unrestricted by the geographical terrain, and can be directly applied to practical demands, such as electric vehicles, large-scale energy storage, and micro-devices. Currently, hundreds of electrochemical energy storage devices have been developed, exhibiting different technical mechanisms and application spaces. [2] Supercapacitors dominate the field of high power applications, while rechargeable metal-ion batteries such as lithium-ion batteries (LIBs) and next-generation metal-ion batteries (low-cost and abundant potassium, sodium, magnesium, zinc, and aluminum battery systems) are expected to govern high energy density applications. [3][4][5] During the discharge process, positive ions migrate from the anode into the cathode and generate electrons, while the charging process is the opposite. [6] During this reversible process, electrode materials are the core components in metal-ion batteries and the main substances in an electrochemical redox reaction and their physical and chemical properties closely correspond to the performance of electrochemical energy storage equipment in either electrolytic or galvanic cell systems. Therefore, developing novel, highly active, multifunctional electrode materials has become a key issue in achieving efficient energy storage and conversion. [7] Currently, cathode materials occupy the most important position in the composition of metal-ion batteries. [8] The properties of cathode materials directly determine the final performance indexes of metal-ion battery products. [9] Moreover, in commercial LIB devices, cathode materials account for about 40% of the cost of the whole cell. [10] However, compared with the fast-developing development of anode materials, the development of cathode materials has been relatively slow. One reason is that it is challenging to prepare highly crystalline cathodes, and even slight changes in the preparation process can lead to great differences in material structures and properties. Another factor is that cathode materials present a low specific capacity relative to anode materials, which directly influences the energy density Metal-organic frameworks (MOFs) and covalent-organic frameworks (COFs) are two emerging families of functional materials used in many fields. Advantages of both include compositional designability, structural diversity, and high porosity, which offer immense possibilities in the search for high-performance electrode materials for metal-ion batteries. A large number of MOF/COF-based cathode materials have been reported. Despite these advantageous fea...

“…11−13 In recent years, most research on rechargeable cathode materials of AZIBs have focused on manganese-based compounds, 6,14−17 vanadium-based compounds, 18−20 Prussian blue analogues, 21,22 and polyanionic compounds. 23,24 Among these materials, layered vanadium-based compounds have been widely regarded as promising cathodes for AZIBs because of their high theoretical capacity and unique multielectron redox reaction based on the V element. 25,26 However, the narrow layer spacing of vanadium-based compounds generally leads to slow zinc ion transport.…”

Ammonium vanadate (NH4V4O10) has attracted considerable focus as a cathode material with great potential for aqueous zinc ion batteries due to its multielectron redox reaction of V and low cost; however, problems such as structural instability and slow reaction kinetics during cycling hinder its widespread application. Herein, ethylene glycol is intercalated into the interlayer of NH4V4O10 to develop high-performance cathodes for aqueous zinc ion batteries. The layer spacing of the material is expanded by ∼23% after the intercalation of ethylene glycol, providing a large interlaminar channel for Zn2+ diffusion, while the addition of ethylene glycol leads to the micromorphology of nanoflowers self-assembled by ultrathin nanosheets, exposing more active sites for ion and electron transport. Moreover, the successful partial substitution of ethylene glycol for NH4 + in the NH4V4O10-based material results in an increase in the level of V5+ and alleviates irreversible deamination, promoting efficient redox reactions. In addition, the introduction of ethylene glycol efficiently decreases the band gap of NH4V4O10 and, thus, improves the conductivity. As a result, the ethylene glycol-intercalated NH4V4O10 cathode provides a high reversible capacity of 516 mAh g–1 at 0.5 A g–1 and achieves an excellent cycling performance with a capacity retention rate of 91% after 1000 cycles at 10 A g–1. This work provides a feasible strategy to develop high-performance layered V-based cathodes for AZIBs by the coregulation of crystal structure, micromorphology, and redox chemistry.

Improving Na‐ion diffusion kinetics is an effective strategy to boost the sodium storage performance of electrode materials for sodium ion batteries (SIBs). Herein, an oxygen vacancy engineering is reported to evidently enhance Na‐ion diffusion kinetics of Na3V2(PO4)3 and accordingly boost sodium storage performance. Na3V2(PO4)3/C with different molar contents of Cu doping (0%, 2.5%, 4%, 5%, and 6%) are synthesized using a simple sol–gel method followed by an annealing treatment. The experimental results show that Cu2+ successfully replaces the V3+ sites of Na3V2(PO4)3 and that does not change its phase composition. The introduction of Cu2+ not only results in the formation of V4+ to maintain charge balance, leading to a shorter VO bond, but also promotes the generation of oxygen vacancies and accordingly facilitates Na‐ion diffusion kinetics. As expected, the optimal sample displays a stable capacity of 111.4 mA h g−1 with capacity retention of 90.4% over 300 cycles at 1 C and a high rate capacity of 83.8 mA h g−1 at 20 C. The studies demonstrate that the Cu doping is favorable for the electrochemical enhancement of Na3V2(PO4)3, which provides a promising prospect for Na3V2(PO4)3 as a cathode for SIBs.
