Manufacturing of lithium-ion battery prototypes through environmentally friendly processes

Abstract

The objective of the Master thesis was to study two safer and greener electrolyte alternatives to the classical liquid organic electrolyte used in lithium-ion batteries. The two alternatives studied were the gel polymer electrolyte and the water-in-salt electrolyte. The lithium-ion batteries investigated were composed of a lithium iron phosphate positive electrode and a lithium titanate oxide negative electrode, both produced through a water-based manufacturing process. The electrochemical performances of the electrodes with the classical liquid electrolyte and the two alternatives were investigated in half-cell and full-cell configurations.
