Di-CF3-EC, solvent for electrolytes Li- based batteries
The invention describes an additive for electrolytes for use in lithium-ion batteries.
High oxidation stability
Reduced safety risk
Lithium ion batteries are widely used as mobile energy storage.
The substance cis-4,5-bis (trifluoromethyl) -1,3-dioxolan-2-one according to the invention makes it possible to use the solvent propylene carbonate, which results in a reduced safety risk compared to conventional ethylene carbonate-based liquid electrolytes. The additive improves SEI formation and has high oxidation stability.
