Abstract Electrolytes engineering plays a crucial role in determining electrode/electrolyte interfacial chemistry for developing high‐voltage lithium metal batteries (HV‐LMBs). Although great progress has been made on electrolytes anodes, the realization of HV‐LMBs severely hindered due to lack advanced that can simultaneously support stable Li anode and cathode (> 4.6 V vs + /Li). Herein, through molecular via strategic monofluorination design, two terminal monofluorinated siloxanes including (2‐fluoroethoxy)trimethylsilane (MFS) bis(2‐fluoroethoxy)dimethylsilane (F2DEO) are designed synthesized. Compared with nonfluorinated counterparts, siloxane‐based not only exhibit higher dielectric constant oxidative stability but also allow weaker solvation ability better compatibility. With “4S” (single salt single solvent) at standard concentration, 1.0 M LiFSI/F2DEO electrolyte endows operation 590 h Li||Li symmetric cells high coulombic efficiency 99.3% Li||Cu half cells. Moreover, Li||LiCoO 2 full achieve high‐capacity retention 85.9% after 200 cycles, which may be attributed F2DEO synergistic effect FSI − regulating interphase. This design strategy provides promising approach future exploration HV‐LMBs.

High-Ni cathodes promise high energy density but suffer from interfacial degradation. Here, a dual-additive electrolyte-trimethylsilyl phosphate to scavenge HF and adiponitrile tailor Li+ solvation-enables robust, LiF-rich CEI, boosting NCM811's stability. This strategy achieves 90.16% capacity retention at 5C, offering pathway durable, high-performance batteries.
