Abstract

Conductometric studies of highly-concentrated solutions of lithium salts have been carried out in 1,2-dimethoxyethane (DME), a low dielectric and high DN (donor number) solvent. The formation constant of the triple ion has been determined and discussed with respect to that obtained from the measurement in a very dilute solution. Direct determination of the molar conductivity of the triple ion pair has been done and compared to conventionally assumed values. The reason for the increase in the conductivity of Li ion containing propylene carbonate (PC) solutions with the addition of DME is discussed. Preferential solvation of the Li ion by solvents with higher DN is proposed as one important factor. The solvation constants of Li ion by solvents with high DN have been determined.
