| Abstract Scope |
Crystalline defects and strain often govern the evolution of operando energy materials, or provide a strong indicator of material state. In contrast to techniques that provide ensemble information across large volumes, imaging allows one to interrogate local structure to build understanding of isolated physical events occurring within operando materials. Bragg coherent x-ray diffraction imaging (BCDI) is a technique that enables nanoscale characterization. Owing to the deeply penetrating nature of hard x-rays, and image contrast derived from Bragg diffraction, we can observe the structural evolution of individual crystalline grains within energy materials at the nanoscale. At the Advanced Photon Source of Argonne National Laboratory a new instrument is being developed that will greatly amplify the spatial/temporal resolution of the technique enabling real time investigations with BCDI. This talk will introduce BCDI and its application to nanoscale imaging of dislocation evolution in individual battery cathode nanocrystals. |
