Inorganic/organic composite fluorinated interphase layers for stabilizing ether-based electrolyte in high-voltage lithium metal batteries
Despite their superior reduction stability to Li metal compared with conventional carbonate electrolytes, ethers have been precluded from use in high-voltage batteries due to their limited oxidation stability (
