Key Points

The aim is to improve the stability of lithium metal batteries under high-voltage and cryogenic conditions by managing interfacial chemistry.
Development of an intramolecularly polarized electrolyte to regulate solvation dynamics.
Formation of dual-gradient interphases with LiF-rich SEI and boroxane-incorporated CEI.
Evaluation of Li||Li symmetric cells and full cells using LiNi0.8Co0.1Mn0.1O2 cathodes.
Li||Li symmetric cells achieved stable cycling over 16,000 hours with minimal polarization of 8.3 mV.
Full cells retained 90% capacity after 1,000 cycles at 4.5 V and maintained 80% at 4.9 V.
3 Ah pouch cells exhibited 509 Wh kg−1 energy density at 30°C with 96.8% capacity retention after 80 cycles.
