  • By unlocking the full performance capabilities of battery materials we require a thorough understanding of the underlying electrochemical mechanisms at a variety of length scales. A broad arsenal of X-ray microscopy and mapping techniques is now available to probe these processes down to the nanoscale. The tunable nature of X-ray sources allows for the extraction of chemical states through spectromicroscopy. The addition of phase contrast imaging can retrieve the complex-valued refraction of the material, giving an even more nuanced chemical picture. Tomography and coherent Bragg diffraction imaging provide a reconstructed three-dimensional volume of the specimen, as well as internal strainmore » information from the latter. There have been many insights into battery materials achieved through the creative use of these, and similar, methods. Experiments performed while the battery is being actively cycled reveal behavior that differs significantly from what is observed at equilibrium and metastable conditions. Furthermore, there are planned improvements to X-ray source brightness and coherence will extend these techniques by alleviating the current trade-off in time, chemical, and spatial resolution.« less

  • The electrochemical energy storage systems based on Li-based insertion and reconstitution chemistries are a vital component of future energy technologies. Development of high energy and power density materials demands detailed understanding of the nanoscale mechanisms involved in Li-battery operation, including the interplay between the interfacial electrochemical reactions, electron and Li-ion diffusion, and structural defects. We demonstrate that strong coupling between Li-ion concentration and lattice parameters can be used as an efficient basis for real-space imaging of Li-ion currents and electrochemical reactivity on the nanometer length scales, providing what until now has been an elusive view of the electrochemical reactivity onmore » a level of single structural element.« less
