Despite extensive research, their practical deployment remains limited by persistent challenges such as polysulfide shuttling and metal anode degradation, which collectively lead to poor coulombic efficiency and limited cycle life. These issues are further intensified in emerging systems employing sodium, potassium, magnesium, calcium, and siliconbased anodes. Fluorinated electrolytes have emerged as a promising approach to address these limitations. Fluorination enhances oxidative stability, suppresses polysulfide dissolution, promotes stable solid–electrolyte interphase (SEI) formation, and improves safety. Although widely studied in lithium-ion and lithium-metal batteries, fluorinated electrolytes remain underexplored in metal–sulfur systems, despite growing evidence of their potential to mitigate key degradation pathways. This review provides a mechanism-focused analysis of fluorinated electrolytes for metal–sulfur batteries, with a particular emphasis on Li–S systems. It begins by assessing the limitations of conventional electrolytes and examines how fluorinated solvents, salts, and additives influence polysulfide solubility, electrode interfacial stability, and overall electrochemical performance. The discussion then extends to emerging non-lithium metal–sulfur systems, where fluorinated electrolytes can improve stability. Environmental and economic considerations are addressed, followed by an outlook on key parameters and target goals for realizing practical metal–sulfur batteries by leveraging fluorinated electrolytes.

This design increases free ion concentration and reduces system viscosity (10.9 mPa s), significantly enhancing bulk ion transport and achieving an ionic conductivity (41.7 mS cm^-1) unattainable by conventional DEEs.

However, their fast-charging capability is hampered at high voltages due to sluggish Li⁺ transport and structural degradation. Herein, we report a heuristic, solid-state co-doping strategy employing boron (B³⁺) and titanium (Ti⁴⁺) to simultaneously engineer the bulk structure and surface chemistry of Ni-rich cathodes. The co-doped materials demonstrate exceptional stability in lithium-graphite full cells, retaining &gt;86% capacity after 500 cycles at a 4C charge rate, even across elevated cutoff voltages (4.3-4.5 V) and high Ni contents (80–100 mol%). Multiscale characterization reveals three critical morphological features: (i) radially arranged nanosheet-like grains that alleviate anisotropic lattice strain; (ii) an in-situ formed Li-B-O surface layer that mitigates electrolyte decomposition at high voltage; and (iii) a defect-mediated cation-mixed interphase that pillars the layered structure under extreme delithiation. Extension of this strategy to ultra-high Ni systems, including LiNi_0.9Co_0.1O₂ and LiNiO₂, yielded comparable enhancements. Mechanistic insights further enabled the rational selection of earth-abundant pillaring elements, enhancing the scalability and sustainability of the proposed doping system.
