Probing the structural and chemical evolutions of advanced energy storage system for high energy density
EMSL Project ID
49573
Abstract
The specific aims of this project are to probe the structure-property relationship of next-generation energy materials (such as energy storage materials) under dynamic operating conditions with a range of spatial (down to atomic) and temporal resolution. This goal will be accomplished by using concerted multiscale in-situ spectroscopic and imaging methodologies based on NMR, TEM, STEM, electron energy-loss spectroscopy (EELS), energy-dispersed x-ray spectroscopy (EDS), SEM/FIB, APT, SEM/FIB, XRD, and SIMS. We will in particular probe energy storage materials related to lithium metal and lithium sulfur system.
