In-situ microscopy and spectroscopy study of structural and chemical evolution of energy materials


EMSL Project ID
60577

Abstract

The objective of the proposed research is to use in-situ transmission electron microscopy (TEM) 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 scanning TEM (STEM) imaging, electron energy-loss spectroscopy (EELS), energy-dispersed x-ray spectroscopy (EDS) and scanning electron microscopy (SEM) combined with focused ion beam (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.
