Presented are electrolyte compositions with fluorinated cosolvents, methods for making/using such electrolyte compositions, and electric-drive vehicles with lithium-ion battery cells using such electrolyte compositions. An electrolyte composition for a lithium-ion electrochemical device includes a lithium salt, a nonaqueous solvent, and a fluorinated cosolvent. The lithium salt may include one or more soluble ionic salts, whereas the solvent may include one or more non-aqueous organic solvents. The fluorinated cosolvent includes a cyclic carbonate with a fluorine atom that is bonded directly to the cyclic ring, to a single atom bonded to the cyclic ring, or to a single side chain group bonded to the cyclic ring. The fluorinated cosolvent may be a fluoroethylene carbonate, a difluoroethylene carbonate, a trifluoropropylene carbonate, or a difluoropropylene carbonate. The side chain group may be an R-group, such as a 3-C chain, with at least one carbon atom bonded directly to the cyclic ring.
