Alternative Solid‐State Synthesis Route for Highly Fluorinated Disordered Rock‐Salt Cathode Materials for High‐Energy Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
This work presents a tailored solid‐state route to enhance DRX fluorination and electrochemical performance. Using unconventional precursors, Li6MnO4, MnF2, and TiO2, prevents Mn‐based intermediates, which do not accommodate fluorines, enabling the formation of highly fluorinated DRX with a composition of Li1.23Mn0.40Ti0.37O2−yFy (y = 0.29–0.34 ...

The limitations of a standard phase-field model in reproducing jointing in sedimentary rock layers [PDF]

arXiv
Geological applications of phase-field methods for fracture are notably scarce. This work conducts a numerical examination of the applicability of standard phase-field models in reproducing jointing within sedimentary layers. We explore how the volumetric-deviatoric split alongside the AT1 and AT2 phase-field formulations have several advantages in ...

Coupling of CuO@NiBiOx Catalyzed Glycerol Oxidation to Carbon Dioxide Reduction Reaction for Enhanced Energy Efficiency

Angewandte Chemie, EarlyView.
A CuOx@NiBiOx core‐shell‐like catalyst is synthesized. Thanks to the Bi presence, the electronic structure of Ni is tuned, leading to better catalytic performance for glycerol oxidation compared to both CuOx and CuOx@NiOx catalysts. Additionally, coupling glycerol oxidation with CO2 reduction significantly reduces the operational voltage and the ...

Metal Sulfides as Potential Materials for Next Generation Lithium Ion Batteries: A Review

Advanced Energy and Sustainability Research, EarlyView.
The flame spray pyrolysis (FSP) method demonstrates its superiority in fabricating metal sulfide‐based electrodes without inactive materials like organic binders or solvents. The particles are directly deposited and compressed onto the electrode surface, integrating into continuous production.

Cake formation in the filtration of associative microgel suspensions

AIChE Journal, EarlyView.
Abstract In this work, we investigate the jamming behavior of associative microgel suspensions used as fluid loss additives in model porous media. We first construct a phase diagram using drying experiments, followed by characterization of the suspensions' rheology and the permeability of the filter cakes at maximum microgel concentration.
