High‐Concentrated Non‐Flammable Electrolytes
In article 2300849, Lei Li, Joseph S. Francisco, Meng Gu, and co‐workers uncover a uniform laminated crystalline‐amorphous structure of the solid electrolyte interphase (SEI) at the atomic scale in high‐concentrated non‐flammable electrolytes using cryo‐high‐resolution transmission electron microscopy (HRTEM). This research yields valuable insights into the stability and lithium conductivity of non‐flammable electrolytes, which can improve the safety of lithium metal batteries.
