Solvated Li+ ions are intercalated into graphite in a dilute glyme-based solution and this reaction has attracted much attention for use in advanced lithium-ion batteries due to their high rate capability. In this study, Li+ co-intercalation behaviors in asym. glymes (CH3O(CH2CH2O)nC4H9, n = 2 or 3) were investigated and compared to those in sym. glymes (CH3O(CH2CH2O)nCH3, n = 1-4). Despite the large alkyl sidechains of asym. glymes, co-intercalation reactions of solvated Li+ proceeded as well as those in sym. glymes. In charge and discharge measurements, the reversible capacities in asym. glyme-based solutions were smaller than those in sym. glymes except for tetraglyme, which showed the lowest reversible capacity. There was no clear difference in the sandwich distances of glyme-Li-GICs calculated from X-ray diffraction patterns of both sym. and asym. glymes. Therefore, solvated Li+ ions with asym. glymes occupied more space in the graphite interlayer compared to sym. glymes, which resulted in smaller reversible capacities for asym. glymes. These results demonstrate the influence of solvent-related structures of GICs on reversible capacities for co-intercalation systems.
