Mixtures of solvents are commonly used in non-aqueous lithium-ion battery electrolytes. Structures comprised of the solvents and ions determine many of the electrolyte properties. Solvation structures which could exist in the electrolyte solution include separated-solvated ions, solvent separated ion pairs, solvated contact ion pairs, and polyionic aggregates. An understanding of these solvent-ion interactions will aid in the selection of solvent mixtures. The experimental techniques that were used in this investigation were Raman scattering, conductivity measurements, and viscosity measurements. The experimental results were supplemented by quantum mechanical ab initio calculations in order to gain further insight into the solvation structures. The possibility of the formation of ion-pairs and the predicted structure of the ion-pair is calculated. The solvent mixtures were made up of ethylene carbonate combined with one of the following solvents: propylene carbonate, diethyl carbonate, or dimethyl carbonate. Lithium perchlorate was used as the electrolyte. This research was the result of constant collaboration between the University of Windsor and General Motors.Dept. of Chemistry and Biochemistry.
