Abstract
Electrolyte compositions comprising fluorinated acyclic carboxylic acid esters, fluorinated acyclic carbonates, and/or fluorinated acyclic ethers; co-solvents; and certain film-forming chemical compounds are described. The electrolyte compositions are useful in electrochemical cells, such as lithium ion batteries where they provide the improved performance of a combination of high capacity and high cycle life.
