Ether-based electrolytes are desired for lithium metal batteries owing to their low reduction potentials; however, they suffer from low anodic stability. Strategic methylation of ether solvents is shown to extend their electrochemical stability and facilitate the formation of LiF-rich interphases, enabling high-voltage lithium metal batteries while avoiding the use of fluorinated solvents.
