Characterization and modeling range from atomic and nano scale to entire battery cells and battery packs.</p> <p>We have used in situ synchrotron X-ray diffraction to study the intercalation/de-intercalation processes in operating batteries, covering both commercial batteries and micro battery cells. A special capillary-based micro battery cell has been developed by us for in situ studies, designed to study structural changes in the electrode materials in detail, and to map chemical/compositional gradients through an electrode layer. In addition, the cell will be used in connection with a new EU project, Hi-C, for studies of internal interfaces in battery electrode crystallites using high resolution synchrotron X-ray powder diffraction. Hi-C will focus on development of in situ methods for characterizing nano-scale external and internal &nbsp;interfaces during operation of electrochemical storage systems</p> <p>Results from in situ studies of structural investigations of cathode and anode materials will be presented together with preliminary results from in situ studies of chemical gradients and interface investigations.</p> <p><strong>Host:</strong> Associate professor Torben René Jensen, iNANO and Department of Chemistry, Aarhus University, Aarhus, Denmark</p> </td> </tr> <tr> <td>&nbsp;</td> <td><p><strong>Please note!<br></strong><strong>Coffee, tea and bread will be served in front of the iNANO auditorium from 10:00 o'clock.</strong></p></td> </tr> </tbody> </table>
