Measurements in Hamburg


From March 15 to March 22, 2023, the measurements at the beamline P01 of the PETRA III synchrotron at DESY in Hamburg were recently carried out within the framework of the project I-20221051 EC "Study of Hard Carbon Electrodes in Na-Ion Battery by Operando X-ray Raman spectroscopy (XRS)". We performed measurements of the carbon absorption edge K (XANES and EXAFS) and the sodium edge K in the cathode of the battery. The analysis of the volume-extended cathode was achieved using X-ray Raman scattering, which enables measurement of the absorption edges of light elements using high-penetrating hard X-ray light. The experiment took place in cooperation with the Laboratory for Modern Battery Systems at the Chemical Institute in Ljubljana, which intensively deals with this topic.
