Abstract: Raman spectroscopy was used for investigation of tape-cast LCO foils. The aim of the work was to test the suitability of a portable and cost-effective Raman spectrometer as a tool for inline monitoring of electrode processing. The influence of device-specific limitations, as well as intrinsic material properties, of LCO electrodes was investigated. It could be shown that the heat impact caused by laser excitation is negligible. Typical electrode properties as roughness or orientation do not significantly influence the Raman measurements. Based on this investigation, Raman spectroscopy is a promising tool for intended inline monitoring.
