Abstract
Disclosed herein are electrolyte compositions comprising: a) a first solvent comprising a cyclic carbonate; b) a second solvent comprising a non-fluorinated acyclic carbonate; c) at least one electrolyte component selected from: i) a fluorinated acyclic carboxylic acid ester; ii) a fluorinated acyclic carbonate; iii) a fluorinated acyclic ether; or iv) a mixture thereof; and d) an electrolyte salt; wherein the electrolyte component is present in the electrolyte composition in the range of from about 0.05 weight percent to about 10 weight percent, based on the total weight of the first and second solvents.
