Developing Three-dimensional characterization methods for energy and environmental materials
EMSL Project ID
48445
Abstract
Three dimensional high resolution nanoscale characterization is pivotal in understanding materials relevant to energy and environmental applications. As a part of this proposal and an LDRD funded by Chemical Imaging Initiative, we aim to develop a combined STXM-TEM-APT multimodal chemical imaging capability to characterize advanced Li, Na ion battery cathode materials and atmospheric aerosols. In the battery portion of the proposed research we aim to utilize state of the art chemical imaging capabilities like APT and aberration corrected TEM for characterizing advanced Li and Na ion battery electrodes both before and after electrochemical cycling. In the second thrust of this proposal we aim to develop high resolution aerosol imaging expertise, including high resolution transmission electron microscopy, atom probe tomography and imaging x-ray photoelectron spectroscopy to characterize coated and bare atmospheric aerosols in collaboration with PNNL atmospheric chemistry scientists.
