A review of the features and analyses of the solid electrolyte interphase in Li-ion batteries
TL;DR: The solid electrolyte interphase (SEI) is a protecting layer formed on the negative electrode of Li-ion batteries as a result of electrolyte decomposition, mainly during the first cycle as discussed by the authors.

The Electrochemical Behavior of Alkali and Alkaline Earth Metals in Nonaqueous Battery Systems—The Solid Electrolyte Interphase Model
TL;DR: In this article, it is suggested that in practical nonaqueous battery systems the alkali and alkaline earth metals are always covered by a surface layer which is instantly formed by the reaction of the metal with the electrolyte.

Advanced Model for Solid Electrolyte Interphase Electrodes in Liquid and Polymer Electrolytes
TL;DR: In this article, the contribution of grain boundary resistance (Rgb) for polyparticle solid electrolytes is shown to be larger than the bulk ionic resistance, and it is shown that the equivalent circuit for such a mosaic-type SEI electrode is extremely complex.

The cathode-electrolyte interface in the Li-ion battery
TL;DR: In this article, the same experimental techniques as used earlier to characterize the composition and properties of the so-called solid electrolyte interphase (SEI) layer formed at the graphite-anode-electrolyte interface of a Li-ion battery are used to acquire some degree of understanding of interface phenomena occurring on the cathode side of the cell, even though the validity of the SEI-layer concept is still somewhat tenuous in this “cathode” context.
