The superlattice crystals–mimic, flexible/functional ceramic membrane is presented as a new ceramic‐driven material/architecture opportunity for next‐generation high‐performance battery separators. The structural uniqueness/Mn 2+ ‐chelating ability of the ceramic membrane (comprising the close‐packed, thiol groups–containing silica particles spatially besieged by the polyvinylpyrrolidone/polyacrylonitrile nanofiber skeleton) enables unprecedented improvement in the membrane properties and, more notably, the high‐temperature cyclability far beyond those accessible with conventional polymeric separators.
