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.
在Li1.3Al0.3Ti1.7(PO4)3 （LATP）与锂（Li）电极之间构建了聚偏二烯烃：BN层，提高了界面相容性和热稳定性。富li3n固体电解质界面调控锂沉积行为。固态锂金属电池（sslmb）表现出优异的电化学性能，在0.2 mA cm-2下可循环800小时，临界电流密度为1.4 mA cm-2。这些研究为sslmb的接口工程提供了指导。
