Intercalation of Li into graphite was performed by a chemical method in various ether-type solvents oftetrahydrofuran (THF), 2-methyl tetrahydrofuran (2-MeTHF), 2, 5-dimethyl tetrahydrofuran (2, 5-diMeTHF), 1, 2-dimethoxyethane (DME), 1, 2-diethoxyethane (DEE), 1, 2-dibutoxyethane (DBE), 1, 2-dimethoxymethane (DMM), 1, 2-diethoxymethane (DEM), 1-methoxypropane (MP), 1-methoxy-butane (MB), diethyl ether (Et2O) and resultant products were studied by X-ray diffraction. For the solvents of THF, DME, DEE, DBE, DMM, DEM, ternary Li-solvent-graphite intercalation compounds (GIC) were obtained. On the contrary, for the other solvents, only Li intercalated into graphite to form binary Li-GIC. The criteria for the solvent co-intercalation were discussedin terms of the electron donicity of the solvents, the size of the solvents and also the size of Li-solvent complexes.
