Integrated Ring‐Chain Design of a New Fluorinated Ether Solvent for High‐Voltage Lithium‐Metal Batteries

Ether-based electrolytes offer promising features such as high lithium-ion solvation power and stable interface, yet their limited oxidation stability impedes application in high-voltage Li-metal batteries (LMBs). Whereas the fluorination of the ether backbone improves the oxidative stability, the resulting solvents lose their Li
