Abstract Vanadium oxide‐based materials are considered to be among the most promising positive electrode candidates for aqueous zinc‐metal batteries (AZMBs). However, complex processes, high costs, and insufficient yields of their preparation methods limit further application. Herein, an efficient effective oil bath method is presented CaV 6 O 16 ·2.7H 2 (CaVO), offering performance as cathode material AZMBs. With commercial crystalline V 5 , Ca(CH 3 COO) water raw materials, phase‐pure CaVO with 42.8 g per batch a yield 98.8% can obtained through reaction at 90 °C h. It demonstrated that pre‐intercalated Ca 2+ H not only expand interlayer spacing from 4.38 Å 8.21 but also stabilize structure vanadium oxides, promoting reversibility toward de‐/intercalation Zn /H + . In addition, density‐functional theory calculations show introduction effectively improves diffusion kinetics in CaVO. As result, provides specific capacity (379 mAh −1 0.05 A ) long‐term cyclability (94.4% retention after 2200 cycles 1 ), demonstrating synthesis high‐performance

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.

As a high-capacity and cost-effective anode, zinc metal is garnering significant attention for aqueous energy storage systems. However, it suffers from serious issues, such as undesirable side reactions, polyiodide shuttle, uncontrolled Zn dendrite growth. Herein, an innovative solution proposed by constructing hybrid artificial interfacial layer on anode surfaces to protect anodes. Benefiting the compact structure negatively charged ionic channels, as-obtained protective can not only promote nucleation accelerate ion migration, thereby resulting in remarkable dendrite-free highly reversible anodes, but also serves armor suppress reactions avoiding corrosion of Consequently, both assembled symmetric cells deliver prolonged cycle life. The work offers promising avenue achieving ultrastable anodes
