Abstract
Disclosed herein are electrolyte compositions comprising a fluorinated solvent, a fluorinated sulfone, at least one component selected from a borate salt, and/or an oxalate salt, and/or a fluorinated cyclic carbonate, and at least one electrolyte salt. The fluorinated solvent may be a fluorinated acyclic carboxylic acid ester, a fluorinated acyclic carbonate, a fluorinated acyclic ether, or combinations thereof. The electrolyte compositions are useful in electrochemical cells, such as lithium ion batteries.
