ED-CSP: Crystal Structure Prediction from Electron Diffraction
Germain Poloudenny, Arnaud Demortière, Yaël Frégier
Recovering a periodic 3D crystal structure from sparse, unindexed electron diffraction (ED) observations is a challenging generative inverse problem. Existing ED-based learning met…
BattVAE-GP: Generative Modeling of Long-Horizon Battery Degradation with Uncertainty Quantification
Raghvender Raghvender, Mahdi Abid, Ferran Brosa Planella +2
Long-horizon physics-based simulations of battery degradation provide mechanistic insight but remain computationally expensive, limiting their use for dense exploration of operatin…
AI-Driven Phase Identification from X-ray Hyperspectral Imaging of cycled Na-ion Cathode Materials
Fayçal Adrar, Nicolas Folastre, Chloé Pablos +7
Na-ion batteries have emerged as viable candidates for large-scale energy storage applica- tions due to resource abundance and cost advantages. The constraints imposed on their per…
Nanoscale Mapping of Transition Metal Ordering in Individual LiNi0.5Mn1.5O4 Particles Using 4D-STEM ACOM Technique
Gozde Oney, Fayçal Adrar, Junhao Cao +8
The electrochemical performance of the spinel LiNi0.5Mn1.5O4, a high-voltage positive electrode material for Li-ion batteries, is influenced by the transition metal arrangement in…
Investigation of Cathode Electrolyte Interphase Formation via Coupling Liquid Electrochemical TEM and GC/MS
Kevyn Gallegos-Moncayo, Josephine Rezkallah, Justine Jean +3
A deeper understanding of the cathode electrolyte interphase (CEI) formation mechanism is essential to elucidate battery degradation. Here, we combine Liquid Electrochemical Transm…
Euclidean Distance to Convex Polyhedra and Application to Class Representation in Spectral Images
Antoine Bottenmuller, Florent Magaud, Arnaud Demortière +2
With the aim of estimating the abundance map from observations only, linear unmixing approaches are not always suitable to spectral images, especially when the number of bands is t…
Unsupervised Multi-Clustering and Decision-Making Strategies for 4D-STEM Orientation Mapping
Junhao Cao, Nicolas Folastre, Gozde Oney +4
This study presents a novel integration of unsupervised learning and decision-making strategies for the advanced analysis of 4D-STEM datasets, with a focus on non-negative matrix f…
Investigation of Microstructural Evolution in All-Solid-State Micro-Batteries through in situ Electrochemical TEM
Sorina Cretu, Nicolas Folastre, David Troadec +7
All-solid-state batteries hold great promise for electric vehicle applications due to their enhanced safety and higher energy density. However, further performance optimization req…
Bi-phasic lithiation/delithiation dynamics in Li-ion batteries: application of the Smoothed Boundary Method in the phase field model
Ahmed Yousfi, Arnaud Demortière, Guillaume Boussinot
An appropriate description of the lithiation/delithiation dynamics in bi-phasic primary cathode particles of Li-ion batteries requires an accurate treatment of the conditions holdi…
