ED-CSP: Crystal Structure Prediction from Electron Diffraction
Germain Poloudenny, Yaël Frégier, Arnaud Demortière
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…
