Title: Polyfluorinated carbonate electrolyte for high-voltage lithium batteries

Abstract

A non-aqueous solvent composition for a lithium battery comprises a fluorinated solvent mixture that consists essentially of a 1,2-difluoroethylene carbonate and a fluoro-substituted dialkyl carbonate in a respective weight ratio of about 1:3 to about 1:1, and optionally up to about 30 wt % of an additional organic solvent. An electrolyte for a lithium ion battery comprises a lithium salt dissolved in a non-aqueous solvent composition comprising the fluorinated solvent mixture.
