Popis: | In view of the high reactivity of the lithium metal, lithium batteries must operate in an aprotic environment, which can either be a conducting polymer, a liquid solvent, or a mixture of them. Two families of aprotic liquids were considered as solvents for lithium bis(trifluoromethylsulfone)imide (LiCF{sub 3}SO{sub 2}NSO{sub 2}CF{sub 3} or LiTFSI). The first one is the substituted sulfamides, R{sub 1}R{sub 2}NSO{sub 2}NR{sub 3}R{sub 4}, where the R groups are either methyl, ethyl, or methoxyethyl (CH{sub 2}CH{sub 2}OCH{sub 3}), and the second one is the glymes, CH{sub 3}O(CH{sub 2}CH{sub 2}O){sub n}CH{sub 3}, for n up to 10. The phase diagrams, potential windows, conductivities, and the lithium interfacial resistances of the solutions were investigated, often as a function of temperature. The potential use of these solvents for different types of batteries is discussed. |
