Abstract
Dehydrated compositions are obtained by: combining a hydrous composition, e.g., a hydrous electrolyte salt, with inert fluorochemical liquid; heating the resulting mixture in a vessel to volatilize water and inert fluorochemical liquid therein until the water content of the mixture is reduced to a desired level; optionally treating the resulting dehydrated mixture with another chemical material, e.g., a polar organic solvent; and optionally subjecting the dehydrated mixture or the treated dehydrated mixture to further treatment, e.g., separation of the mixture. Liquid electrolytes suitable for use in battery applications can be prepared by this method.
