Synchrotron radiation based operando characterization of battery materials / Black Serra, Ashley Phillip (Institut de Ciència de Materials de Barcelona) ; Sorrentino, Andrea (ALBA Laboratori de Llum de Sincrotró) ; Fauth, François (ALBA Laboratori de Llum de Sincrotró) ; Yousef, Ibraheem (ALBA Laboratori de Llum de Sincrotró) ; Simonelli, Laura (ALBA Laboratori de Llum de Sincrotró) ; Frontera, Carlos (Institut de Ciència de Materials de Barcelona) ; Ponrouch, Alexandre (Institut de Ciència de Materials de Barcelona) ; Tonti, Dino (Institut de Ciència de Materials de Barcelona) ; Palacín, M. Rosa (Institut de Ciència de Materials de Barcelona)
Synchrotron radiation based techniques are powerful tools for battery research and allow probing a wide range of length scales, with different depth sensitivities and spatial/temporal resolutions. Operando experiments enable characterization during functioning of the cell and are thus a precious tool to elucidate the reaction mechanisms taking place. [...]

$Operando Synchrotron X-ray Diffraction in Calcium Batteries$

10 p, 7.7 MB

Operando Synchrotron X-ray Diffraction in Calcium Batteries : Insights into the Redox Activity of 1D CaCoMO (M = Co and Mn) / Black Serra, Ashley Phillip (Institut de Ciència de Materials de Barcelona) ; Monti, D. (Institut de Ciència de Materials de Barcelona) ; Frontera, Carlos (Institut de Ciència de Materials de Barcelona) ; Tchitchekova, Deyana (Institut de Ciència de Materials de Barcelona) ; Houdeville, Raphaëlle (ALBA Laboratori de Llum de Sincrotró) ; Fauth, François (ALBA Laboratori de Llum de Sincrotró) ; Palacín, M. Rosa (Institut de Ciència de Materials de Barcelona)
1D CaCoMO (M = Co z = 0, M = Mn z = 1, and M = Fe z = 0. 4) were prepared and tested electrochemically. While the iron-containing phase was not found to be active, the iron- and manganese-containing phases were found to be potentially interesting as positive electrode materials for calcium metal-based high-energy battery technologies and were investigated by operando synchrotron X-ray diffraction. [...]

Unveiling a New High-Temperature Ordered Magnetic Phase in ϵ-Fe2O3 / García-Muñoz, José Luis (Institut de Ciència de Materials de Barcelona) ; Romaguera, Arnau (Institut de Ciència de Materials de Barcelona) ; Fauth, François (ALBA Laboratori de Llum de Sincrotró) ; Nogués, Josep (Institut Català de Nanociència i Nanotecnologia) ; Gich García, Martí (Institut de Ciència de Materials de Barcelona)
Iron oxides are among the most abundant materials on Earth, and yet there are some of their basic properties which are still not well-established. Here, we present temperature-dependent magnetic, X-ray, and neutron diffraction measurements refuting the current belief that the magnetic ordering temperature of ϵ-FeO is ∼500 K, i. [...]

$Synchrotron powder diffraction on operando batteries at non-ambient temperature$

145 p, 8.3 MB

Synchrotron powder diffraction on operando batteries at non-ambient temperature / Houdeville, Raphaëlle ; Fauth, François, dir. ; Palacín, M. Rosa, dir.
L'objectiu d'aquesta tesi ha estat el desenvolupament de cel·les electroquímiques termalizadas per a estudis de materials d'elèctrode in situ mitjançant difracció de raigs X en bateries operant. [...]
El objetivo de esta tesis ha sido el desarrollo de celdas electroquímicas termalizadas para estudios de materiales de electrodo in situ mediante difracción de rayos X en baterías operando. La motivación global para la construcción de dichas celdas es la investigación de sistemas con cinética lenta, de materiales con transiciones de fase dependientes de la temperatura y/o procesos de envejecimiento acelerados por la temperatura. [...]
The aim of this thesis is to develop and test new thermalized in situ cells for X-ray diffraction in operando batteries to facilitate studies on electrode materials. The general reason for developing such cells is to study systems with slow kinetics, materials with temperature dependent phase transitions and/or temperature accelerated ageing processes. [...]
