Perfluorinated Sulfonyl Fluoride Mediated Solvation and Interphase Dual Engineering in a Weakly‐Solvating Electrolyte for High‐Voltage Li‐Metal Pouch Cell
The practical deployment of high‐voltage Ni‐rich lithium‐metal batteries is hindered by severe electrolyte decomposition at both electrodes. Herein, we design a weakly‐solvating electrolyte (WSE) with fluoroethylene carbonate (FEC) and 2,2,2‐trifluoroethyl methyl carbonate (FEMC) as solvents. This electrolyte promo...
