As emerging cutting-edge energy storage technologies, aqueous zinc-ion batteries (AZIBs) have garnered extensive research attention for its high safety, low cost, abundant raw materials, and, eco-friendliness. Nevertheless, the commercialization of AZIBs is mainly limited by insufficient development cathode materials. Among potential candidates, MXene-based materials stand out as a promising option their unique combination hydrophilicity and conductivity. However, Zn2+ kinetics, structural instability, narrow interlayer spacing MXenes hinder practical application. Comprehensively addressing these issues remains challenge. Herein, different ion pre-embedded V2CTx are constructed to tune spacing, with findings showing NH4 + pre-intercalation more effective. To accelerate it proposed first time zinc-philic engineering that can effectively reduce migration barrier, achieved decorating +-intercalated (NH4-V2CTx) ZnO nanoparticles. Various analyses theoretical calculations prove there strong coupling effect between V2CTx, which notably boosts reaction kinetics stability. The ZnO-decorated NH4-V2CTx exhibits reversible capacity 256.58 mAh g-1 at 0.1 A excellent rate capability (173.07 2 g-1). This study pioneers strategy modification in AZIBs.

Abstract Aqueous zinc‐ion batteries (AZIBs) have garnered significant interest for their potential in large‐scale energy storage, attributed to high safety and low cost. Nonetheless, issues such as limited cycling lifespan coulombic efficiency (CE) associated with dendrite formation uncontrollable side reactions on the Zn metal anode pose challenges that restrict practical applications. Herein, a dielectric filler‐assisted artificial hybrid interphase is constructed surface address faced by aqueous electrolytes. TiO 2 nanoparticles special properties promote solvation process carboxymethyl cellulose (CMC) acts physical barrier suppressing adverse blocking dendrite. Consequently, symmetric cell using modified zinc achieves prolonged cycle life of over 2500 h at 1 mAh cm −2 . Furthermore, full vanadium‐based cathode delivers excellent electrochemical performance (over 600 cycles A g −1 ). This research offers an efficient scalable approach enhance anodes.

Abstract Aqueous Zn–I 2 batteries have considerable potential owing to their environmental friendliness and high safety. However, the slow iodine conversion kinetics shuttle effect prevent practical applicability.
