M.)--Brown University, 2019</mods:note><mods:genre authority="aat">theses</mods:genre><mods:abstract>Lithium metal batteries are a promising energy storage solution due to their high theoretical gravimetric capacity (3780 mAh/g), lithium’s low density (0.534 g/cm3), and low reduction potential (-3.04 V compared to Standard Hydrogen Electrode). However, these batteries suffer from rapid capacity loss and safety concerns due to dendrite growth. Their implementation has been hampered by the lack of an operando imaging technique to study them. Spatial Frequency Heterodyne X-ray Imaging (SFHXI) is a non-synchrotron, non-destructive technique that allows for measurement of X-ray scatter at hundreds of thousands of image points in unmodified cells. Due to the large field of view associated with SFHXI, statistical information of the cells is able to be obtained, an unprecedented advantage of this technique. The character of the plated lithium surface and the growth of the solid electrolyte interphase were studied in unmodified lithium metal half cells. It was found that the scatter intensity is related to the surface morphology at that region, allowing for monitoring the inhomogeneity of the cell. These results can lead to the improvement and implementation of these high performing batteries.</mods:abstract><mods:subject><mods:topic>Li-ion Batteries</mods:topic></mods:subject><mods:subject><mods:topic>batteries</mods:topic></mods:subject><mods:subject authority="fast" authorityURI="http://id.worldcat.org/fast" valueURI="http://id.worldcat.org/fast/01764640"><mods:topic>Lithium ion batteries</mods:topic></mods:subject><mods:subject><mods:topic>Solid Electrolyte Interphase</mods:topic></mods:subject><mods:subject><mods:topic>X-ray imaging</mods:topic></mods:subject><mods:language><mods:languageTerm authority="iso639-2b">English</mods:languageTerm></mods:language><mods:recordInfo><mods:recordContentSource authority="marcorg">RPB</mods:recordContentSource><mods:recordCreationDate encoding="iso8601">20190603</mods:recordCreationDate></mods:recordInfo><mods:identifier type="doi">10.26300/1zg4-vw93</mods:identifier><mods:accessCondition type="rights statement" xlink:href="http://rightsstatements.org/vocab/InC/1.0/">In Copyright</mods:accessCondition><mods:accessCondition type="restriction on access">Collection is open for research.</mods:accessCondition></mods:mods>
