Knowledge about degradation and failure of Li-ion batteries (LIBs) is of paramount importance especially because failure can be accompanied by severe hazards. To contribute to the understanding of such phenomena synchrotron in-line phase contrast Xray tomography was employed to investigate internal cell deformation and degradation caused by an internal short circuit (ISC). The tomographic images taken from an uncycled Li/Li cell and a short-circuited Li/Li cell reveal how lithium microstructures (LmS) develop during electrochemical stripping and plating during discharge and charge and how the three-layer separator used is damaged by growing LmSs and delaminates and melts as a consequence of an ISC. Previously unknown insights into the internal cell degradation and deformation mechanisms caused by an ISC are obtained and provide hints of how the properties of the separator could be modified in order to improve the reliability and safety of current and next-generation LIBs.

Investigation of Energy‐Relevant Materials with Synchrotron X‐Rays and Neutrons

Many materials used for energy conversion have a complex structure and chemical composition, knowledge of which is important for both understanding the function of materials and energy conversion systems and for their further development. Synchrotron radiation and neutrons can make an important contribution to understanding the function of such systems. Taking examples from the fields of fuel cells, gas separation membranes, batteries, solar cells, and catalysts, the use of radiography, tomography, diffraction, scattering, and absorption edge spectroscopy is demonstrated. The strength of such methods is the in situ characterization of processes and compositions, and so the focus is on these aspects.

“…Hard x-ray radiography and microtomography using synchrotron light sources are established techniques, applied nowadays to a broad set of scientific fields such as biology, medicine, materials science, environmental research, geosciences, and paleontology [1][2][3][4]. The performance of a synchrotron imaging station is directly connected to its coherence properties as well as the amount of monochromatic photon flux available.…”
