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.

甲基化为锂金属电池提供高压醚电解质

由于其低还原电位，锂金属电池需要基于醚的电解质；然而，它们的阳极稳定性较低。醚溶剂的策略性甲基化被证明可以延长其电化学稳定性并促进富含 LiF 的中间相的形成，从而实现高电压锂金属电池，同时避免使用氟化溶剂。
