Abstract:
A polyvinylidene carbonate:BN layer was constructed between Li1.3Al0.3Ti1.7(PO4)3 (LATP) and the lithium (Li) electrode, improving interfacial compatibility and thermal stability. The Li3N-rich solid electrolyte interphase regulates Li deposition behaviors. The solid-state Li metal batteries (SSLMBs) show remarkable electrochemical performance, exhibiting endurance for 800 hours of cycling at 0.2 mA cm-2 and a critical current density of 1.4 mA cm-2. These studies provide guidance for interface engineering in SSLMBs.
