"Molecular-level Characterization of the Solid Electrolyte Interphase in Lithium Ion Batteries"
The composition and structure of the solid electrolyte interphase that forms on the surface of electrodes in lithium ion batteries is believed to play a key role in controlling performance. We use solid-state NMR spectroscopy to provide a detailed characterization of the discrete organic and inorganic species that comprise this interphase. We examine the interphase that forms in different electrolyte formulations and correlate with differences in battery efficiency, allowing us to rationalize the role of specific electrolyte components.
