The　electrode-electrolyte　interfaces　play　pivotal　roles　in　alkali-metal　batteries,　necessitating　superior　electrochemical　stability,　excellent　electrical　insulation,　and　high　ionic　conductivity.　This　study　proposes　using　zeolites　as　interfacial　protective　layers　owing　to　their　inherently　high　stability　with　both　alkali　metals　and　high-voltage　cathodes　as　well　as　exceptionally　wide　band　gaps　that　minimize　electron　transport.　To　further　pinpoint　zeolites　with　rapid　ionic　diffusivity　among　their　versatile　structures,　we　devise　a　universal　approach　to　explore　diffusion　dynamics　in　arbitrary　structures.　Through　first-principles　calculations,　we　identify　the　diffusion　networks　of　Li+,　Na+,　and　K+　in　22,　17,　and　4　zeolites,　respectively.　Eventually,　we　predict　5,　7,　and　3　zeolites　as　suitable　interfacial　protective　layers　for　Li-,　Na-,　and　K-metal　batteries,　respectively,　each　characterized　by　a　diffusion　barrier　below　0.3　eV.　This　research　automates　the　exploration　of　diffusion　dynamics　in　complex　materials　and　underscores　the　significant　potential　of　zeolites　as　interfacial　protective　layers　in　alkali-metal　batteries.　©　2025　American　Chemical　Society.
