Tóm tắt

Lithium phosphorus oxynitride (LiPON) is one of the few solid electrolytes that form a truly passivating solid electrolyte interphase (SEI) when in contact with metallic lithium. Investigations into the origin of this stability may provide the insights needed to replicate it in the SEIs of alternative solid electrolyte materials. In this study, we used in situ lithium plating X-ray photoelectron spectroscopy (XPS) to investigate the formation and evolution of the Li-LiPON SEI. We show that the SEI is chemically and structurally inhomogeneous, with the fully reduced compounds identified in previous studies (Li
