This study examines how current collector chemistry and electrodeposition rate affect microstructure of sodium metal and its solid electrolyte interphase. Synchrotron X-ray nanotomography, grazing-incidence wide-angle X-ray scattering, and cryogenic focused ion beam microscopy reveal differences in film morphology, internal porosity, and crystallographic preferred orientation. Mesoscale modeling delineates the role of SEI on electrodeposit growth and onset of electrochemical instability.
