Porosity of Solid Electrolyte Interphases on Alkali Metal Electrodes with Liquid Electrolytes

ACS Applied Materials & Interfaces, 2021
Despite the fact that solid electrolyte interphases (SEIs) on alkali metals (Li and Na) are of great importance in the utilization of batteries with high energy density, growth mechanism of SEIs under an open-circuit potential important for the shelf life and the nature of ionic transport through SEIs are yet poorly understood. In this work, SEIs on Li/

Non-fluorinated non-solvating cosolvent enabling superior performance of lithium metal negative electrode battery

Nature Communications, 2022
Localised high-concentration electrolyte is key to prevent uneven growth of lithium metal by forming a mechanically stable solid-electrolyte interphase. Here, the authors identify the suitable physicochemical properties for non-solvating co-solvents that

Interfaces and Interphases in All-Solid-State Batteries with Inorganic Solid Electrolytes [PDF]

Chemical Reviews, 2020
All-solid-state batteries (ASSBs) have attracted enormous attention as one of the critical future technologies for safe and high energy batteries. With the emergence of several highly conductive solid electrolytes in recent years, the bottleneck is no longer Li-ion diffusion within the electrolyte. Instead, many ASSBs are limited by their low Coulombic

Direct Observation of Inhomogeneous Solid Electrolyte Interphase on MnO Anode with Atomic Force Microscopy and Spectroscopy

, 2012
Solid electrolyte interphase (SEI) is an in situ formed thin coating on lithium ion battery (LIB) electrodes. The mechanical property of SEI largely defines the cycling performance and the safety of LIBs but has been rarely investigated.

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 ...

Understanding the failure process of sulfide-based all-solid-state lithium batteries via operando nuclear magnetic resonance spectroscopy

Nature Communications, 2023
All-solid-state lithium batteries performance is affected by the solid electrolyte interphase (SEI) and electrically disconnected (“dead”) Li metal. Here, via operando NMR measurements, the authors quantify the Li metal in the SEI and “dead” regions ...

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 ...

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
