Abstracts
SiO₂ and Al₂O₃ nano fillers were added to an electrolyte composed of a solution 1 M LiPF₆ in tetra ethylene glycol dimethyl ether (TEGDME) and the effects of these nano powders on capacity and cycling performances were investigated. Galvanostatic charge/discharge (GC) measurements were performed in the assembled Li-air cells by using the nanocomposite electrolytes. The discharge capacities of these cells were cyclically tested by a battery tester at a constant current in the voltage range between 2.15 V and 4.25 V. Discharge products of nanocomposite electrolytes were characterized by SEM and XRD spectroscopies. The electrochemical results demonstrated that Al₂O₃ reinforced electrolyte showed higher discharge capacity and cyclability than those of SiO₂ reinforced electrolyte.
