Abstract

Some important properties of the electrolytes used in Li-air batteries were investigated. Electrolyte composed of a solution of 1 M LiPF6 in tetra ethylene glycol dimethyl ether (TEGDME) was reinforced with SiO2, Al2O3, poly(ethylene) oxide (PEO) and tris (pentafluorophenyl) borane (TPFPB) additives. The eects of these reinforcements on conductivity, viscosity and thermal stability were investigated. Electrical conductivity tests were carried out using a multiparameter meter. Viscosity tests were performed in a viscometer using tuning-fork vibration method. Thermal stability of the electrolytes was tested by both TG and DSC.
