Inorganic/organic composite fluorinated interphase layers for stabilizing ether-based electrolyte in high-voltage lithium metal battery

The synergistic effect strategy based on dual salt and fluoroethylene carbonate (FEC) as a co-solvent induces more robust inorganic/organic composite (SEI/CEI) fluorinated interphase layers (SEI/CEI), providing ether-based electrolytes for high-voltage lithium metal batteries.
