In the quest to overcome obstacles encountered by zinc anodes and side reactions in aqueous zinc-ion batteries (AZIBs), researchers have presented a variety of innovative strategies. This research focuses on an approach engineering angstrom pores (4.32 Å-8.57 Å), serve as ion channels that selectively restrict transport [Zn(H2O)6]2+ ions based size exclusion principles. Moreover, utilization nitrogen-enriched MET-6 zincophilic sites enhances adsorption Zn2+ ions, thereby facilitating their desolvation process. Through rigorous experimental analysis corroborated computational simulations, it was demonstrated MET-6@Zn composite, serving artificial solid electrolyte interphase, can effectively suppress ensure maintenance homogeneous electric fields fluxes, which directed uniform deposition realized high-performance Zn metal anodes. Notably, symmetric cells integrated with electrodes exhibited remarkable stability continuous cycling for up 3200 h at current density 0.5 mA cm-2. addition, full equipped KVOH cathodes maintained impressive capacity retention rate, retaining 82% initial after 1250 cycles 8 A g-1, marking substantial enhancement comparison performance bare electrodes. The integration confined presents promising strategy stabilizing anodes, providing solutions persistent challenges AZIB technology.
