“How can advanced transmission electron microscopy contribute to battery research? .
Artem M. Abakumov - Skoltech, Russia and University of Antwerp, Belgium
Artem M. Abakumov is full professor and associate director at the Skolkovo Institute of Science and Technology (Skoltech). Before joining Skoltech, Artem worked at the EMAT laboratory for seven years as a research leader. The design and improvement of the cathode materials for Li-ion batteries requires detailed knowledge on the crystal structure at different charge/discharge states and comprehensive understanding of the processes occurring at the nanoscale or even atomic scale level. Advanced transmission electron microscopy (TEM) is by far the most suitable and direct tool to look at the materials down to atomic scale. Recent progress in the quantitative electron diffraction methods and aberration-corrected scanning TEM imaging will be illustrated here with examples of atomic structure investigation of various cathode materials.
“Current topics in battery research at GREENMAT, ULiege, Belgium”
Benedicte Vertruyen - University of Liège, Belgiumspan>
Benedicte Vertruyen is currently Professor at the Department of Chemistry of the University of Liège and assists Prof. R. Cloots in the management of the GREENMAT group. Before her appointment in 2008 she had been pre-doctoral/post-doctoral researcher of the “National Fund for Scientific Research” (FNRS, Belgium). In 2003, she obtained a PhD at ULg for a research work focusing on the influence of microstructure on the magnetoresistivity of manganite oxides, in collaboration with CRISMAT (Caen, Prof. B. Raveau). As a post-doctoral researcher, she was involved in several research projects and international collaborations on different types of materials, establishing thereby her expertise in X-ray diffraction of polycrystalline materials. Her current research interests include the crystal chemistry of functional oxides and the synthesis of these materials as powders or thin films through solution routes, preferably aqueous.
"Battery electrode materials: a crystallographer's playground"
Gwenaelle Rousse - Collège de France, France
Gwenaelle Rousse is associate professor at Sorbonne University and Collège de France (Paris, France). She is specialized in crystallographic studies and Rietveld refinements from X-ray and neutron powder diffraction and she has worked for more than 10 years on battery materials. She will illustrate in her talk how powder diffraction can give valuable insights while studying electrode materials for Li-ion batteries, and can also be interesting for other scientific communities such as condensed matter physics.
