Abstract: Interfaces play an important role in determining coulombic efficiency, energy efficiency, energy density, power density, cycle performance, service life, safety and self-discharge rate of lithium-ion batteries. We first briefly summarize our understanding of the formation mechanisms and structure of solid electrolyte interphase (SEI). We then introduce experimental techniques for characterizing the SEI including transmission electron microscopy (TEM), atomic force microscopy (AFM), and TG-DSC-MS.

Key words: interface, solid electrolyte interphase, characterization, lithium ion batteries
