Polymer electrolytes are one of the most intensively studied materials nowadays as candidates for new generation solid state batteries. These types of electrolytes are indisputable materials for all Li metal batteries including lithium-sulphur (Li-S). The work presented here covers corrosion investigation of the aluminium current collector in modelled polymer electrolytes. The influence of temperature, polysulfides presence and different salts: lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) and lithium 2-trifluoromethyl-4,5-dicyanoimidazole (LiTDI) were investigated. In-situ techniques, microscope Raman spectroscopy allowed to analyse corrosion pits creation on aluminium electrodes. The investigation was supported by SEM microimaging, computational modelling and half cell cycling. Different electrochemical methods confirmed the creation of a non soluble Al_2S_3 product. Additionally, LiTDI salt reduces corrosion of aluminium in half cell.
