Aqueous zinc ions batteries (AZIBs) using non-organic electrolytes have garnered sustained interest as a future energy storage technology, primarily due to their low cost, environmental friendliness, and intrinsic safety. However, ion suffer from series of serious challenges, including hydrogen evolution reaction (HER) at the anode, surface passivation, dendrite formation, well limited operating voltage comparatively density. These factors are all influenced by concentration H+ in electrolyte (i.e., pH), its fluctuations during cycle process. To date, there remains lack systematic evaluation correlation between pH value challenges faced AZIBs, or focused review how influences electrochemical performance AZIBs strategies that can be used improve cell efficiency. In this we emphasize strong detail research progress made recent years relating additives, separator modification, interfacial protective layers, battery system design, with particular focus on regulatory mechanisms associated control. On basis, propose important focuses suggestions for onward development AZIBs.

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.
