Combining X-ray Nano-CT and XANES Techniques for 3D Operando Monitoring of Lithiation Spatial Composition evolution in NMC Electrode

Autor: Nguyen, Tuan-Tu, Xu, Jiahui, Su, Zeliang, De Andrade, Vincent, Franco, Alejandro A., Delobel, Bruno, Delacourt, Charles, Demortière, Arnaud

In this study, we present a well-defined methodology for conducting Operando X-ray absorption near-edge structure spectroscopy (XANES) in conjunction with transmission X-ray nano computed tomography (TXM-nanoCT) experiments on the LiNi$_{0.5}$Mn$_{0.

The Impact of Inter-grain Phases on the Ionic Conductivity of LAGP Solid Electrolyte Prepared by Spark Plasma Sintering

Autor: Cretu, Sorina, Bradley, David G., Kudu, Omer Ulas, Feng, Li Patrick Wen, Nguyen, Linh Lan, Nguyen, Tuan Tu, Jamali, Arash, Chotard, Jean-Noel, Seznec, Vincent, Hanna, John V., Demortière, Arnaud, Duchamp, Martial

Li1.5Al0.5Ge1.5(PO4)3 (LAGP) is a promising oxide solid electrolyte for all-solid-state batteries due to its excellent air stability, wide electrochemical stability window and cost-effective precursor materials. However, further improvement in their

Morphological Evolution of NMC Secondary Particles Through in situ electrochemical FIB/SEM experiment

Autor: Cadiou, François, Nguyen, Tuan-Tu, Bettge, Martin, Su, Zeliang, Ando, Jonathan, De Andrade, Vincent, Miller, Dean, Demortière, Arnaud

Microstructural evolution of NMC secondary particles during the battery operation drives the electrochemical performance and impacts the Li-ion battery lifetime. In this work, we develop an in situ methodology using the FIB/SEM instrument to cycle si

Adorym: A multi-platform generic x-ray image reconstruction framework based on automatic differentiation

Autor: Du, Ming, Kandel, Saugat, Deng, Junjing, Huang, Xiaojing, Demortiere, Arnaud, Nguyen, Tuan Tu, Tucoulou, Remi, De Andrade, Vincent, Jin, Qiaoling, Jacobsen, Chris

We describe and demonstrate an optimization-based x-ray image reconstruction framework called Adorym. Our framework provides a generic forward model, allowing one code framework to be used for a wide range of imaging methods ranging from near-field h
