Use of perfluorinated two-five carbon carboxylic acid amides as solvent (component) for salt conductors in electrolytes, e.g. for rechargeable batteries

摘要

Amides of perfluorinated 2- 5C carboxylic acids are used as solvents or solvent components. The amides are used as solvent (components) for salt conductors in electrolytes. Independent claims are also included for the following: (a) amides of formula R1-C(=NH)-R4 (II); (b) mixtures comprising salt conductors and the amides. R1CF3, C2F5 or C4F9; R45- or 6 ring amino group optionally containing 1 or 2 further heteroatoms.
