Solid-state batteries are a promising technology for high-energy-density and safe storage systems. Understanding defect formation within these batteries is crucial for future development, and nondestructive analytical tools are needed for characterizing key components. In this study, defocused micro-SORS was used to analyze typical components of solid-state batteries, allowing for depth profiling spectra to be obtained and demonstrating the technique's potential for nondestructive chemical analysis.
Solid-state batteries represent a promising technology in the field of high-energy-density and safe storage systems. Improving the understanding of how defects form within these cells would greatly facilitate future development, which would be best served by applying nondestructive analytical tools capable of characterization of the key components and their changes during cycling and/or aging. Spatially offset Raman spectroscopy (SORS) represents a potentially useful technique, but currently there is a lack of knowledge regarding its use in this field. To fill this gap, we present an investigation into the use of simple defocused micro-SORS on systems constructed using typical components found within solid-state cells. By analyzing the constituents and the assembled system, it was possible to obtain depth profiling spectra and show that spectra may be obtained from layers which are normally obscured, demonstrating the technique's potential for nondestructive chemical analysis of the subsurface. In this way, the results presented validate the potential of micro-SORS as a technique to develop to support future solid-state battery development, as well as the nondestructive battery analytical field.
