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.

Thermal Stability and Reducibility of Oxygen-Containing Functional Groups on Multiwalled Carbon Nanotube Surfaces: A Quantitative High-Resolution XPS and TPD/TPR Study
TL;DR: In this article, the thermal stability and reducibility of oxygen-containing functional groups on the surface of nitric acid-treated multiwalled carbon nanotubes (CNTs) have been studied using temperature-programmed desorption and reduction (TPD and TPR) and high-resolution X-ray photoelectron spectroscopy (XPS).

A new look at the solid electrolyte interphase on graphite anodes in Li-ion batteries
TL;DR: In this article, conclusive results concerning the chemical composition of the inorganic part of the solid electrolyte interphase (SEI) is described. But the results show that Li2O often reported to be present in the SEI could be an artifact from abusive Ar+ sputtering; the compound is not observed in anodes extracted from hermetically sealed cells that are never exposed to air.
