Abstract: This study examines the morphological changes for a lithium surface immersed in 1 mol dmï€3 LiPF6 dissolved in propylene carbonate containing 1,2-dimethoxyethane as a co-solvent. A passivation film was formed on the surface of the lithium metal by electrolyte decomposition. Atomic force microscopy and electrochemical impedance spectroscopy results revealed that there were no direct correlations between the changes in the surface morphology of the lithium metal, and the resistance behavior of its passivation film.
