Journal ArticleDOI
Origin of additional capacities in metal oxide lithium-ion battery electrodes
Yan-Yan Hu,Zigeng Liu,Kyung-Wan Nam,Olaf J. Borkiewicz,Jun Cheng,Xiao Hua,Matthew T. Dunstan,Xiqian Yu,Kamila M. Wiaderek,Lin-Shu Du,Karena W. Chapman,Peter J. Chupas,Xiao-Qing Yang,Claire P. Grey,Claire P. Grey +14 more
TL;DR: High-resolution multinuclear/multidimensional solid-state NMR techniques are used with in situ synchrotron-based techniques to study the prototype conversion material RuO2, demonstrating a protocol for studying the structure and spatial proximities of nanostructures formed in this system, including the amorphous solid electrolyte interphase that grows on battery electrodes.
Journal ArticleDOI
Capturing metastable structures during high-rate cycling of LiFePO4 nanoparticle electrodes
Hao Liu,Fiona C. Strobridge,Olaf J. Borkiewicz,Kamila M. Wiaderek,Karena W. Chapman,Peter J. Chupas,Clare P. Grey,Clare P. Grey +7 more
TL;DR: The results demonstrate the formation of a nonequilibrium solid solution phase, LixFePO4 (0 < x < 1), during high-rate cycling, with compositions that span the entire composition between two thermodynamic phases, LiFe PO4 and FePO4.
Journal ArticleDOI
Reversible magnesium and aluminium ions insertion in cation-deficient anatase TiO2

Morgan,Monique Body,Christophe Legein,Walid Dachraoui,Walid Dachraoui,Mattia Giannini,Mattia Giannini,Mattia Giannini,Arnaud Demortière,Arnaud Demortière,Mathieu Salanne,Mathieu Salanne,François Dardoize,Henri Groult,Olaf J. Borkiewicz,Karena W. Chapman,Peter Strasser,Damien Dambournet,Damien Dambournet +21 more
TL;DR: A new strategy to achieve reversible Mg2+ and Al3+ insertion in anatase TiO2 is demonstrated, achieved through aliovalent doping, to introduce a large number of titanium vacancies that act as intercalation sites.
Journal ArticleDOI
Tracking sodium-antimonide phase transformations in sodium-ion anodes; insights from operando pair distribution function analysis and solid-state NMR spectroscopy
Phoebe K. Allan,John M. Griffin,Ali Darwiche,Olaf J. Borkiewicz,Kamila M. Wiaderek,Karena W. Chapman,Andrew J. Morris,Peter J. Chupas,Laure Monconduit,Clare P. Grey +9 more
TL;DR: Variable temperature 23Na NMR experiments reveal significant sodium mobility within c-Na3Sb; this is a possible contributing factor to the excellent rate performance of Sb anodes and is linked to the different reactivity of these networks.
Journal ArticleDOI
The AMPIX electrochemical cell: a versatile apparatus for in situ X-ray scattering and spectroscopic measurements
Olaf J. Borkiewicz,Badri Shyam,Kamila M. Wiaderek,C. Kurtz,Peter J. Chupas,Karena W. Chapman +5 more
TL;DR: The AMPIX cell as mentioned in this paper enables experiments providing greater insight into the complex processes that occur in operating batteries by allowing the electrochemical reactions to be probed at fine reaction intervals with greater consistency with potential for new time-dependent kinetic studies or studies of transient species.
