Structural and chemical evolutions of advanced energy storage system
EMSL Project ID
50058
Abstract
The objective of the proposed research is 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.
