Artificial SEI for Superhigh‐Performance K‐Graphite Anode

open access: yesAdvancement of science, 2021
Although graphite with its merits of low cost, abundance, and environmental friendliness is a potential anode material for potassium ion batteries (PIBs), it suffers from a limited cycle life due to a severe decomposition of the solid electrolyte ...

Coupling Liquid Electrochemical TEM and Mass‐Spectrometry to Investigate Electrochemical Reactions Occurring in a Na‐Ion Battery Anode

open access: yesSmall Methods, Volume 8, Issue 12, December 19, 2024.
In this study, a novel approach for investigating the formation of solid electrolyte interphase (SEI) in Na‐ion batteries through the coupling of in situ liquid electrochemical TEM and gas‐chromatography mass‐spectrometry is proposed. To optimize this coupling, experiments are conducted on the sodiation of hard carbon materials using two different ...

A Perspective on the Molecular Modeling of Electrolyte Decomposition Reactions for Solid Electrolyte Interphase Growth in Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, Volume 34, Issue 30, July 24, 2024.
The inorganic/organic interface within the solid electrolyte interphase of lithium‐ion batteries is likely the place where the electrolyte decomposition reactions occur. The current progress on molecular modeling techniques (e.g., DFT, force fields, machine learning potentials) of the SEI and the challenges each method faces is discussed.

Poisson brackets and Poisson spectra in polynomial algebras

open access: yes, 2012
Poisson brackets on the polynomial algebra C[x,y,z] are studied. A description of all such brackets is given and, for a significant class of Poisson brackets, the Poisson prime ideals and Poisson primitive ideals are determined.

Multiscale Investigation of Sodium‐Ion Battery Anodes: Analytical Techniques and Applications

open access: yesAdvanced Energy Materials, Volume 14, Issue 15, April 19, 2024.
Here, several analytical methods across multiple time and length scales are discussed, covering a wide range of physical and (electro)chemical properties. To fully grasp the complexity of sodium‐ion battery anodes, integrated studies on the same battery system, ranging from the cellular level to the atomic level, are required.
