Advanced microscopy probing of structural and chemical evolution of interfaces in rechargeable batteries


EMSL Project ID
51717

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.The objective of the proposed research is to probe the interfacial structure and chemistry of next-generation energy storage materials, such as rechargeable batteries, under dynamic operating conditions with a range of spatial and temporal resolution. This goal will be accomplished by using concerted multiscale ex-situ, in-situ and cryogenic microscopy and spectroscopic methodologies based on STEM imaging, electron energy-loss spectroscopy (EELS), energy-dispersed x-ray spectroscopy (EDS) and SEM/FIB. The study will lead to the establishment of structure-property relationship, which can be used to guide the designing of materials with enhanced properties.
