Battery technology is a vital part of all aspects of today’s society, but we still lack a basic understanding of some of the processes involved in energy storage. Studying the local electronic structure is key to this understanding, and one tool used to do this is x-ray spectroscopy. Using this apparatus that was developed by at the University of Washington Physics and Clean Energy Institute it is possible to perform in situ x-ray spectroscopy of battery fatigue over many discharge cycles. Previously, x-ray spectroscopy has only been possible at synchrotron beamlines, so a long baseline study like this would have been impossible without the XANES apparatus. XANES Video
