New bis(trifluorine methyl)-dioxolane-one used as solvent for electrolyte for lithium-based energy storage for lithium-ion secondary battery for portable electronics

摘要

A 4,5-bis(trifluorine methyl)-1,3-dioxolane-2-one is new. A 4,5-bis(trifluorine methyl)-1,3-dioxolane-2-one, or its diastereomere, dnantiomere and/or racemate, is new. Independent claims are included for the following: (1) usage of 4,5-bis(trifluorine methyl)-1,3-dioxolane-2-one as solvents for electrolytes; (2) electrolyte; (3) lithium-based energy storage; and (4) manufacture of cis-4,5-bis(trifluorine methyl)- 1,3-dioxolane-2-one.
