TL;DR: In this paper, a study aimed at characterizing by mean of scanning electron microscopy (SEM) the texture of metallic lithium, the influence of cycling parameters, such as current densities and liquid electrolyte formulation, on lithium stripping mechanisms and the lithium deposits morphologies on various lithium surface states (in and ex situ prepared through electrochemical means, physical procedures such as polishing and Pulsed Laser Deposition technique).

TL;DR: It is shown that Li alkyl carbonates can be identified at the electrode's surface by a combined analysis of XPS core peaks and valence spectra.

TL;DR: In this paper, X-ray photoelectron spectroscopy was used to determine the nature and composition of electrode/electrolyte interfaces forming during the 55°C cycling of Li-based cells in ethylene carbonate:dimethyl carbonate LiPF 6 electrolyte using a heat-treated stainless steel substrate as the positive electrode.

TL;DR: A thorough knowledge of degradation mechanisms will enable us to propose new electrolyte formulations to optimize nanocomposite-based lithium ion battery performance, and possible chemical or electrochemical pathways are proposed to account for their formation.

TL;DR: In this article, the identification of carbonate-based electrolyte degradation species formed during high-temperature cycling of Li/M-O cells has been studied in the synthesis and characterization of lithium-based alkyl carbonates.
