Abstract
Disclosed herein are non-aqueous electrolyte compositions comprising a fluorinated solvent, a carbonate co-solvent, at least one 2-furanone derivative, and at least one electrolyte salt. In some embodiments, the electrolyte compositions further comprise a cyclic sulfate. 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.
