Abstract Vanadium‐based compounds as promising cathode materials for aqueous zinc‐ion batteries (AZIBs) have aroused significant attention owing to their multiple oxidation states, layered open‐framework structure, and excellent zinc storage performance. However, the low intrinsic conductivity, slow reaction kinetics poor structure stability greatly hindered widespread application. Herein, nanostructured K0.486V2O5@RuO 2 composite, nanorod‐like potassium vanadate (K0.486V2O5) surface‐modified with nanosized ruthenium dioxide (RuO ), was successfully prepared using a facile one‐step hydrothermal method applied material of AZIBs. Benefiting from surface modification conductive pseudo‐capacitive nanosized‐RuO , composite electrode demonstrates enhanced electrochemical properties accelerated behavior, including superior rate capability reversible capacities 265, 231, 204, 184, 158, 115 mAh·g −1 at current densities 0.1, 0.2, 0.5, 1, 2, 5 A·g respectively, long cycle life 83% capacity retention after 5000 cycles 87% 10,000 10 . This work provides new insights into development high‐performance vanadium‐based

Abstract Rechargeable zinc‐ion batteries (ZIBs) have gained significant attention as potential next‐generation energy storage systems, owing to their inherent safety, environmental benignity, and cost‐effectiveness. However, the substantial electrostatic repulsion of Zn ion results in a sluggish kinetics for its insertion into cathode material. Meanwhile, formation hydrated ionic groups with increased mass volume aqueous electrolyte further hampers transport ability zinc ions, significantly impacting overall electrochemical performance (including capacity, density, rate‐capability, cyclability) batteries. This review systematically summarized recent progress regulation strategy kinetics. The as‐reported mechanisms are introduced ZIBs (Zn 2+ insertion/extraction mechanism, H + or 2 O/ co‐insertion/extraction conversion reaction coordination mechanism). Then, material design fast including soft lattice construction, doping effects, defect introduction, morphology control, interface is summarized. Finally, it concluded future research directions, such high‐entropy design, multi‐scale simulation, machine study, providing roadmap developing high‐performance at ultralow operation temperatures.
