Stabilizing Solid‐state Lithium Metal Batteries through In Situ Generated Janus‐heterarchical LiF‐rich SEI in Ionic Liquid Confined 3D MOF/Polymer Membranes

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(39)

Published: May 30, 2023

Pursuing high power density lithium metal battery with safety is essential for developing next-generation energy-storage devices, but uncontrollable electrolyte degradation and the consequence formed unstable solid-electrolyte interface (SEI) make task really challenging. Herein, an ionic liquid (IL) confined MOF/Polymer 3D-porous membrane was constructed boosting in situ electrochemical transformations of Janus-heterarchical LiF/Li3 N-rich SEI films on nanofibers. Such a 3D-Janus SEI-incorporated into separator offers fast Li+ transport routes, showing superior room-temperature conductivity 8.17×10-4 S cm-1 transfer number 0.82.
