Abstract

Physical characterizations of some lithium salt solutions in n-butylamine, such as apparent molar volumes, viscosity, vapour pressure measurements, solvation numbers by NMR spectroscopy, electrical conductivities, electroactivity range … have been carried out showing that this amine is a good solvent for lithium batteries. Three salts were used, LiNO3, LiTrif and LiTFSI. Solutions of lithium triflate or LiTFSI are stable toward lithium and possess a good conductivity (better than 3 × 10−3 S cm−1 at + 20 °C) for concentrations far from the saturation (the maximum of conductivity laying within the salt mole fraction interval 0.1–0.2 for LiSO3CF3 · xn-Bu) and an electroactivity range of 4.5 V at a smooth Pt electrode.
