Title: Fluoro-substituted ethers and compositions

Abstract

Described herein are fluoro-substituted ethers of Formula (I): wherein R1 is a fluoro-substituted C2-C6 alkyl group; R2 is a C2-C6 alkyl group or a fluoro-substituted C2-C6 alkyl group; each R3 independently is H, F, methyl, or fluoro-substituted methyl; and n is 0, 1, 2, 3, or 4. The fluoro-substituted ether compounds are useful as solvents for lithium containing electrolytes in lithium batteries, particularly lithium-sulfur batteries.
