Spiderweb‐mimicking anion‐exchangeable separators are presented as a membrane‐driven strategy for the development of high‐performance Li‐S batteries by Sang‐Young Lee and co‐workers in article number 1801422 . The polyionic liquid (PVIm[TFSI])‐based nanomat in the spider separator enables discharge voltage‐dependent, reversible trap/release of polysulfides via an anion exchange reaction between TFSI − anions and polysulfides. The seperator's unique nanomat structure and chemical functionalities exceptionally improve the electrochemical performance of Li‐S batteries.
