ConspectusZinc-ion batteries (ZIBs) are highly promising for large-scale energy storage because of their safety, high energy/power density, low cost, and eco-friendliness. Vanadium-based compounds attractive cathodes versatile structures multielectron redox processes (+5 to +3), leading capacity. Layered or 3-dimensional open tunnel frameworks allow easy movement zinc-ions without breaking the structure apart, offering superior rate-performance. However, challenges such as dissolution phase transformation hinder long-term stability vanadium-based in ZIBs. Although significant research has been dedicated understanding mechanisms developing high-performance cathodes, uncertainties still exist regarding critical dissolution, actual active specific optimization strategy. For example, it is unclear whether materials α-V

Abstract Vanadium‐based aqueous zinc‐ion batteries (AZIBs) exhibit significant potential for large‐scale energy storage applications, attributed to their inherent safety characteristics. Addressing the slow transport kinetics of divalent Zn 2+ within cathode lattice, thereby enhancing rate capability and stability, is essential Zn‐V battery system.

Abstract Zinc‐ion batteries (ZIBs) show great promise for next‐generation energy storage, but their performance at low temperatures is severely hindered by sluggish desolvation kinetics cathode‐electrolyte interface. To address this limitation, a zincophilic‐hydrophobic poly(3,4‐ethylenedioxythiophene) (PEDOT) modified layer proposed on V 5 O 12 •6H 2 cathode. Ab initio molecular dynamics simulations indicate that modification strategy promotes Zn ⁺ adsorption and reduces the free dissociating hydrated 2+ to form interface, across temperature of 280 240 K. As result, PEDOT‐modified cathode exhibits significantly improved diffusion kinetics, delivering superior rate with remarkable capacity 226.5 mAh g⁻¹ 40 A g⁻¹. Notably, even −30 °C, maintains high 268.3 mA 0.2 robust retention (92.4%) over 1,000 cycles 1 This approach markedly improves low‐temperature operational efficiency, highlighting potential interface engineering advance zinc‐ion in cold environments.

Abstract The sustainable utilization of natural resources and growing demand for various electronic devices have promoted the development safe, stable, rechargeable aqueous zinc‐ion batteries (AZIBs). However, a stable cathode material is crucial ZIBs in an electrolyte, since it more difficult divalent Zn 2+ to be reversibly inserted extracted between active materials than monovalent metal ions.
