Abstract Lacking strategies to simultaneously address the narrow interlayer spacing, irreversible phase transitions, dissolution and electrical transport issues of vanadium oxides is restricting their application in aqueous zinc‐ion batteries. Herein, these challenges concurrently, an organic‐inorganic hybrid cathode explored, HNaV 6 O 16 ·4H 2 O‐Glu (HNVO‐Glu), through a guest material‐mediated NVO synthesis strategy utilizing glutamic acid (Glu) induce Na substituted by proton enable crystal transformation V ·3H (NVO). Specially, Glu insertion kills three birds with one arrow: i) induces formation structurally stable monoclinic introducing H into framework, preventing structural change collapse material; ii) acts as pillar expand which improves Zn 2+ diffusion kinetics; moreover, polar groups on surface weaken electrostatic interaction between host materials, further enhancing zinc‐ionic rate; iii) enhances conductivity HNVO converting p‐type semiconductor n‐type structure. Consequently, HNVO‐Glu exhibits high specific capacity (354.6 mAh g −1 at 1 A ), excellent capability (10 −9 10 −7 cm s ) outstanding cycling stability retention 87.2% after 12 000 cycles .

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.

Hydrated vanadium oxides with high theoretical specific capacities and open crystal structures are promising cathodes for aqueous Zn-ion batteries (AZIBs). However, the sluggish Zn2+ diffusion poor electrochemical stability remain challenges in battery applications. In this work, Mn ions effectively confined within interlayer of layered oxide nanobelts through a preintercalation mechanism. The serve as structural pillars to extend spacing, connect adjacent layers, partially reduce pentavalent cations tetravalent states. This expansion spacing reduces electrostatic interactions, while metal enhance electrical conductivity facilitate charge transport. Consequently, it significantly promotes rapid reversible intercalation or (de)intercalation AZIBs.
