However, conventional electrolytes usually exhibit insufficient thermodynamic stability, leading to aggressive lithium dendrites growth and severe cathode-electrolyte reactions, particularly at high voltage (≥ 4.5 V vs. Li/Li<sup>+</sup>). Herein, we propose a design strategy for a strong association electrolyte (SAE) that reduces Li<sup>+</sup>-solvent coordination number, facilitating the formation of ion pairs or ion clusters, even with conventional lithium salt concentrations (1 M). Lithium salts with high cluster formation constant (K<sub>A</sub>), such as lithium difluorophosphate (LiDFP) and lithium nitrate (LiNO<sub>3</sub>), create an SAE with anion-dominated solvation structure, which promotes the formation of aggregates (AGGs) solvate species. This unique solvation structure facilitates the formation of a dense, inorgain rich solid electrolyte interphase (SEI) on lithium metal anode. Additionally, the preferential adsorption of anion clusters at the cathode interface constructs a Li<sup>+</sup>-anions enriched double electric layer (EDL), stabilizing the LiNi<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>O<sub>2</sub> (NCM811) interface. The Li||NCM811 batteries with a 4.5 V high cut-off voltage achieved stable cycling over 1400 cycles with a capacity retention rate of 84 %. Furthermore, 2.5 Ah pouch cells demonstrate superior cycle performance at 4.3 V cut-off voltage and 0.6 A/3 A charge/discharge currents.

In this study, we investigate the effect of a bifunctional additive, trimethylsilyl 2,2-difluoro-2-(fluorosulfonyl)acetate (TDFA), on lithium metal batteries, with a focus on its role in promoting uniform lithium deposition and enhancing interfacial stability. Surface analysis shows that the additive forms a LiF-rich solid-electrolyte interphase (SEI) layer, which is chemically stable and mechanically robust.

In Li/LFP cells, TDFA improves capacity retention to 89.4 % after 300 cycles, with reduced polarization and enhanced rate performance.
