2D and 3D Imaging of Li-Ion Battery Materials Using Synchrotron Radiation Sources

Characterization of microstructural properties in electrodes for Li-Ion batteries can be regarded a key factor to understand functionality and aging process in the cells. X-ray microscopy has proven extremely powerful to capture a number of morphological parameters such as porosity, tortuosity or particle size distribution but also chemical information regarding phase distribution, state of charge or elemental migration over a large range of length scales. With their high penetration power utilizing various contrast methods X-rays offer deep insight into the battery materials and microstructural characteristics
