Modelling of gas permeation through ceramic coatings produced by thermal spraying

open access: yes, 2008
An analytical model has been developed for simulation of gas permeation through thermal spray coatings, and for prediction of the permeability. The model is based on a geometrical representation of the coating microstructure.

Decoding Gas Evolution Pathways and Interfacial Chemistry in Layered Oxide Cathodes for Safer Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Gas evolution behaviors of sodium layered oxide cathodes with varying compositions, cutoff voltages, dopants, and particle sizes/morphologies have been systematically investigated by online electrochemical mass spectrometry. The fundamental outgassing mechanisms of sodium‐based cathodes compared to lithium‐based cathodes have been elucidated.

Mitigating Thermal Runaway in Lithium Metal Batteries With Flame‐Retardant Magnesium Hydroxide Nanocomposite Gel Electrolytes

open access: yesAdvanced Energy Materials, EarlyView.
Lithium‐ion batteries are ubiquitous but pose significant safety risks especially with high‐energy‐density electrode materials. This study reports a nanocomposite gel electrolyte (NGE) with a flame‐retardant magnesium hydroxide (MH) matrix, which offers robust mechanical properties, high ionic conductivity, and enhanced thermal safety.

How Particle Size Affects Consolidation Behavior, Strain and Properties of Li6PS5Cl Fast Ionic Conductors

open access: yesAdvanced Energy Materials, EarlyView.
The densification process of Li6PS5Cl powders with varying particles size distributions reveals differences in smaller and larger distributions. Higher strain is revealed for the smaller particle size distribution from X‐ray diffraction. Discrete element method simulations uncover that the reason for the higher strain is not the particle size itself ...

Experimental Isolation of Single Impact, Cumulative Energy, Aging, and Liquid‐Assisted Grinding Effects in Mechanochemical Reactions

open access: yesAngewandte Chemie, EarlyView.
An experimental framework is introduced to isolate single‐impact and cumulative energy within a mechanochemical system. The guided, stepwise approach highlights the fundamental roles of impact events, post‐impact reactivity, and liquid‐assisted grinding additives in all‐solid mechanochemical reactions.
