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
