Conventional LiF-forming electrolytes rely on anion-rich Li+ solvation, which inevitably lowers the electrolyte ionic conductivity and compromises both fast-charging capabilities and low-temperature performance. Now it has been shown that solvent-bridged electrolytes effectively broaden the liquid range of LiPF6–ether electrolytes, thereby overcoming the intrinsic trade-off between the LiF-rich solid–electrolyte interphase and high ionic conductivity.
