Preparation and in-situ spectroscopic characterization of high-energy density lithium-sulphur batteries

This work was composed of two main parts. In a first step, a electrochemical cell was developed, which could allow the in-situ, in-operando analysis of the functioning battery. The processes taking place inside a running lithium-sulphur cell were then observed and identified with the help of Raman spectroscopy. In a second step, the performance of the cell was studied while using novel cathode materials, as well as modified commercial separators.
