Abstract
Abstract The formation of a stable solid electrolyte interphase (SEI) is a prerogative for functional lithium metal batteries. Herein, the formation and evolution of such SEI in contact with glyme‐based electrolytes is investigated under open circuit voltage and several constant current cycles. An important conclusion of the study is that Li x S y species are nonbeneficial SEI components, compared to the Li 3 N counterpart. In addition, chemical (X‐ray photoelectron spectroscopy, XPS) and electrochemical (impedance spectroscopy) evolution of SEI under galvanostatic conditions are comprehensively tracked.
