Electrolytes based on organic carbonate solvents of ethylene carbonate (EC) and diethyl carbonate (DEC) were prepared by using LiPF₆ as the Li-source. Nano sized Al₂O₃ (50 nm) was used as a reinforcing component in order to control corrosion and Li₂CO₃ formation. Corrosion of the Li foil anode and electrochemical tests were performed by using EC/DEC/LiPF₆ and nanocomposite EC/DEC/LiPF₆/5wt.% Al₂O₃ electrolytes. Electrochemical tests were performed in the swagelok cells by using Li foil anode and carbon air cathode electrodes. Structural tests were carried out by using scanning electron microscopy (SEM), x-ray diffraction (XRD) and Raman spectroscopy. Results revealed that incorporation of nano Al₂O₃ leads to a decrease of corrosion rate of Li anode and a small decrease in the capacity of the air cells.
