Vanadium-based materials have been extensively studied as promising cathode for zinc-ion batteries because of their multiple valences and adjustable ion-diffusion channels. However, the sluggish kinetics Zn-ion intercalation less stable layered structure remain bottlenecks that limit further development. The present work introduces potassium ions to partially substitute ammonium in vanadate, leading a subtle shrinkage lattice distance increased oxygen vacancies. resulting vanadate exhibits high discharge capacity (464 mAh g-1 at 0.1 A g-1) excellent cycling stability (90% retention over 3000 cycles 5 g-1). electrochemical properties battery performances are attributed rich introduction K+ replace NH4+ appears alleviate irreversible deammoniation prevent structural collapse during ion insertion/extraction. Density functional theory calculations show has modulated electron better diffusion path with lower migration barrier.

Abstract Aqueous zinc–ion batteries (ZIBs) have been promptly developed as a competitive and promising system for future large‐scale energy storage. In recent years, vanadium (V)‐based compounds, with diversity of valences high electrochemical‐activity, widely studied cathodes aqueous ZIBs because their rich reserves theoretical capacity. However, the stubborn issues including low conductivity sluggish kinetics, plague smooth application in ZIBs. Among various countermeasures, defect engineering is believed an effective method to alleviate above limitations. This review highlights challenges different V‐based cathode materials (e.g., oxides vanadates) summarizes advances strategies types effects defects, designed strategies, characterization techniques high‐energy Finally, several sound prospects this fervent field are also rationally proposed fundamental research practical application.

High-energy-density lithium-ion batteries (LIBs) that can be safely fast-charged are desirable for electric vehicles. However, sub-optimal lithiation potential and low capacity of commonly used LIBs anode cause safety issues energy density. Here we hypothesize a cobalt vanadate oxide, Co2VO4, attractive material fast-charging due to its high (~ 1000 mAh g-1) safe 0.65 V vs. Li+/Li). The Li+ diffusion coefficient Co2VO4 is evaluated by theoretical calculation as 3.15 × 10-10 cm2 s-1, proving promising in LIBs. A hexagonal porous nanodisk (PCVO ND) structure designed accordingly, featuring specific surface area 74.57 m2 g-1 numerous pores with pore size 14 nm. This unique succeeds enhancing electron transfer, leading superior performance than current commercial anodes. As result, the PCVO ND shows initial reversible 911.0 at 0.4 C, excellent (344.3 10 C cycles), outstanding long-term cycling stability (only 0.024% loss per cycle confirming feasibility
