Raman spectroscopy is a method for investigating the inelastic photon scattering on solids and molecules. The method provides an opportunity for determination of the collective lattice vibrations called phonons. Therefore Raman spectroscopy offers itself for characterizing and investigating important properties e.g. the conductivity of typical electrode materials, such as graphite and silicon. During this Masters project, in-operando imaging of battery cells will be implemented.
