Title: Stabilizing solid electrolyte-anode interface in Li-metal batteries by boron nitride-based naoncomposite coating

Abstract

Solid-state lithium metal batteries are promising to improve safety and energy density compared with conventional Li-ion batteries. However, various high-performance and low-cost solid electrolytes are incompatible with lithium, which is indispensable for enhancing energy density. In this work, we usher in a chemically inert and mechanically robust boron nitride (BN) film as the interfacial protection to preclude the reduction of Li 1.3Al 0.3Ti 1.7(PO 4) 3 (LATP) solid electrolyte by lithium, which is validated by in-situ transmission electron microscopy. When combined with ~1-2 µm PEO polymer electrolyte at the Li/BN interface, Li/Li symmetric cells show a cycle life over 500 hours at 0.3 mA·cm -2. Yet, the same configuration but with bare LATP dies after 81 hours. The LiFePO 4/LATP/BN/PEO/Li solid-state batteries show high capacity retention of 96.6% after 500 cycles. This study offers a general strategy to protect solid electrolytes that are unstable against the lithium, and open possibilities for adopting them in solid-state lithium metal batteries.
