Combining operando X-ray techniques to study lithium ion batteries

CoverImageOperando X-ray tomographic microscopy (SRXTM) and scanning X-ray diffraction (SXRD) have been combined for the first time to study dynamic processes in a lithium ion battery. This combination of techniques allowed the lithiation processes to be tracked throughout the electrodes on different length scales: the dynamic distribution of crystallographic phases was analysed using SXRD, while SRXTM data was used to probe volumetric changes and understand the interplay of different kinetic limitations.
