Lithium metal stripping beneath the solid electrolyte interphase [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance This study explores the stripping of lithium anodes under various current densities and in different liquid electrolyte systems. We discovered nanovoid formation between the lithium and the solid electrolyte interphase (SEI).

The Role of Phosphorous in the Solid Electrolyte Interphase of Argyrodite Solid Electrolytes
The solid electrolyte interphase that forms on Li6PS5Cl argyrodite solid electrolytes has been reported to continually grow through a diffusion-controlled process, yet this process is not fully understood. Here, we use a combination of electrochemical and X-ray photoelectron spectroscopy techniques to elucidate the role of phosphorus in this growth ...

Completing the Picture of the Solid Electrolyte Interphase [PDF]
Joule, 2019 Although solid electrolyte interphase (SEI) formation is an important factor in battery performance, difficulties in characterizing the SEI mean that it is still not well understood. In this issue of Joule, Nanda and coworkers utilize tip-enhanced Raman spectroscopy to paint a more complete picture of the SEI on silicon electrodes.

Linking structure to function at the solid electrolyte interphase: Insights from NMR spectroscopy [PDF]
The performance of Li metal batteries is tightly coupled to the composition and properties of the solid electrolyte interphase (SEI). Even though the role of the SEI in battery function is well understood (e.g., it must be electronically insulating and ...

Chemical Decomposition of the TFSI Anion under Aqueous Basic Conditions
PRX Energy, 2022 Understanding the interfacial reactivity of aqueous electrolytes is crucial for their use in future batteries. We investigate the reactivity of the bis(trifluoromethane)sulfonimide anion when exposed to a strongly basic medium, by means of ab initio ...

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions
Advanced Functional Materials, EarlyView.DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries
