Conductance of solutions of lithium bis(trifluoromethanesulfone)imide in water,propylene carbonate,acetonitrile and methyl formate at 25°C

Conductance data for lithium bis(trifluoromethanesulfone)imide, LiN(CF₃SO₂)₂, are reported for the solvents water, propylene carbonate, acetonitrile and methyl formate at 25°C. Limiting molar conductivitiesA₀, association constants K_A, and triple ion formation constants K_t are reported where applicable. These data are compared with literature data for the commonly studied lithium salts LiClO₄ and LiAsF₆. Non-coulombic energy contributions to ion pair formation are evaluated and discussed in terms of ion-ion and ion-solvent interactions.
