Local-to-Global Fluorination Framework Guides the Discovery of a High-Stability Solvent for High-Voltage Batteries. (A) Schematic diagram describing general guidelines for electrolyte design from the local sites and molecules. (B) Influence of IE and FF, simplified as an electrochemical reaction with an activation energy. (C) Fluorination strategy for the anisole molecule. The bottom shows the ESP maps of the corresponding molecules. (D) Comparison of the IE of designed fluorinated solvent molecules. (E) Comparison of the fmax− value on the methyl group of the designed fluorinated solvent molecules. (F) Electrochemical stability window of designed electrolytes by LSV in a coin cell with Al foil as the working electrode and Li metal as the counter electrode at a scanning rate of 0.1 mV s−1.
