Application of X-ray 3D Imaging in the Field of Battery Materials Research

With human''s growing need for reusable energy, advanced characterization methods become more and more essential in the fields of battery materials research. With the X-ray imaging techniques, we are able to acquire the structure, morphology and strain information of energy materials from 2D and 3D angles at the time-resolution level. In addition, in-situ experiments can be designed with the high-penetration X-rays and the high-brilliance synchrotron sources to track the qualitative and quantitative changes of the samples during charging/discharging. In this paper, the synchrotron-based X-ray imaging technologies and the associated applications are reviewed. The application of several major X-ray imaging technologies, including X-ray projection imaging, transmission X-ray microscopy imaging, scanning transmission X-ray microscopy imaging, X-ray fluorescence microscopy imaging, and coherent diffraction imaging, in the field of battery materials research are introduced, and the future application and development direction of X-ray imaging are prospected.
