The use of poly(1,3-dioxolane) (PDOL) electrolyte for lithium batteries has gained attention due to its high ionic conductivity, low cost, and potential large-scale applications. However, compatibility with Li metal needs improvement build a stable solid interface (SEI) toward metallic anode practical batteries. To address this concern, study utilized simple InCl3 -driven strategy polymerizing DOL building LiF/LiCl/LiIn hybrid SEI, confirmed through X-ray photoelectron spectroscopy (XPS) cryogenic-transmission electron microscopy (Cryo-TEM). Furthermore, density functional theory (DFT) calculations finite element simulation (FES) verify that the SEI exhibits not only excellent insulating properties but also fast transport Li+ . Moreover, interfacial electric field shows an even distribution larger flux, resulting in uniform dendrite-free deposition. Li/Li symmetric steady cycling 2000 h, without experiencing short circuit. provided rate performance outstanding stability LiFePO4 /Li batteries, specific capacity 123.5 mAh g-1 at 10 C rate.

Abstract Widening the voltage window of nickel‐rich layered oxide cathode‐based lithium metal batteries (LMBs) can effectively improve energy density rechargeable batteries. However, serious safety issues associated with high reactivity between LiNi 0.8 Co 0.1 Mn O 2 (NCM811) and electrolyte at cut‐off remains challenging. Herein, a flame‐retardant ability to form robust armor‐like electrode interphase (EEI) LiF Li x B y z compounds for stabilizing Li||NCM811 is proposed. Such exhibits thermal stability effect ensuring battery voltage. The EEI protect both NCM811 (Li) improving cycling performance. As result, capacity retention rate cathode such reached 68% after 150 cycles 4.6 V. This work provides an effective reference reasonable design high‐voltage, electrolytes LMBs.
