Small, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 16, 2025

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.
