Dual-shell LiF@spinel coating enhances lithium-rich cathode stability. Schematic illustration and electrochemical performance of lithium-rich cathodes with and without the LiF@spinel dual shell. The protective design suppresses HF-induced corrosion, prevents transition metal dissolution, and maintains a thin, stable CEI, resulting in significantly higher capacity retention (81.5% vs. 63.2%) after 150 cycles.
