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. ...

A fast 4D look into materials and substances

A project is developing an AI-based software framework that can process terabyte-sized 4D tomography data on a desktop PC

23-Jun-2023 - To visualize processes at the micrometer scale, such as the discharge of a battery, scientists, so far, have required powerful computers that took days, if not months, to analyze large amounts of 4D tomography data. In the joint project “KI4D4E”, researchers are planning an open source framework ...

When soft spheres make porous media stiffer

Researchers of the University of Stuttgart and the University if Twente succeed in three-dimensional characterization

23-Jun-2023 - Porous media such as concrete physically represent a spherical packing of different components – in this case cement, rock and water. The mechanical properties of such mixtures are still difficult to calculate due to their discretized nature. A team led by Prof. Holger Steeb (University of ...
