Volumetric Imaging for Better Batteries

In this talk, I will describe the importance of understanding structure-performance relationships to achieve the full potential of complex, heterogeneous systems, such as lithium ion batteries. To characterize structure and structural dynamics in these multiscale materials, we leverage a variety of imaging techniques including electron and x-ray microscopy to understand the origins of performance limitations and develop design guidelines to systematically improve material and devices.  My talk will present several examples, including the role of nanoscale structure and surface chemistry on electrolyte infilling in lithium ion batteries and lithium transport. I will address the experimental and computational challenges associated with studying these systems and emphasize ways machine learning techniques can be used to overcome these challenges.
