Unique X-ray microscope paves the way to more powerful batteries

New insights into the morphological and chemical changes in battery materials

21-Nov-2024 - New cathode materials are being developed to further increase the capacity of lithium batteries. Multilayer lithium-rich transition metal oxides (LRTMOs) offer particularly high energy density. However, their capacity decreases with each charging cycle due to structural and chemical changes. ...

Tomography shows high potential of copper sulphide solid-state batteries

Processes during charging and discharging observed

30-Nov-2022 - Solid-state batteries enable even higher energy densities than lithium-ion batteries with high safety. A team led by Prof. Philipp Adelhelm and Dr. Ingo Manke succeeded in observing a solid-state battery during charging and discharging and creating high-resolution 3D images. This showed that ...

Using neutrons and X-rays to analyse the ageing of lithium batteries

11-Feb-2020 - An international team has used neutron and X-ray tomography to investigate the dynamic processes that lead to capacity degradation at the electrodes in lithium batteries. Using a new mathematical method, it was possible to virtually unwind electrodes that had been wound into the form of a compact ...

Tomoscopy: new imaging method

Thanks to a world record in tomography, synchrotron radiation can be used to watch how metal foam forms

22-Aug-2019 - An international research team at the Swiss Light Source (SLS) has set a new tomography world record using a rotary sample table developed at the HZB. With 208 three-dimensional tomographic X-ray images per second, they were able to document the dynamic processes involved in the foaming of liquid ...

3D tomographic imagery reveals how lithium batteries age

09-May-2019 - Lithium batteries lose amp-hour capacity over time. Microstructures can form on the electrodes with each new charge cycle, which further reduces battery capacity. Now an HZB team together with battery researchers from Forschungszentrum Jülich, the University of Munster, and partners in China have ...

Fastest 3D tomographic images at BESSY II

10-Aug-2018 - An HZB team has developed an ingenious precision rotary table at the EDDI beamline at BESSY II and combined it with particularly fast optics. This enabled them to document the formation of pores in grains of metal during foaming processes at 25 tomographic images per second - a world record. The ...
