Abstract
Provided is a non-aqueous electrolyte comprising a lithium salt; an organic solvent; and a compound represented by Formula 1 as an additive: wherein in Formula 1, R1 may be an alkyl group having 1 to 5 carbon atoms and optionally being substituted with fluorine, an aryl group having 6 to 8 carbon atoms and optionally being substituted with fluorine, or a nitrile group; and R2 to R4 are each independently an alkyl group having 1 to 5 carbon atoms.
Claims14
A non-aqueous electrolyte, comprising a lithium salt;
- an organic solvent;
- and a compound represented by Formula 1 as an additive:
- wherein in Formula 1, R1 is selected from an alkyl group having 1 to 5 carbon atoms and being substituted with a fluorine, an aryl group having 6 to 8 carbon atoms and being substituted with a fluorine, or a nitrile group;
- and R2 to R4 are each independently an alkyl group having 1 to 5 carbon atoms,
- provided when R2 to R4 are each methyl, R1 is an alkyl group having 1 to 5 carbon atoms and being substituted with at least three fluorine atoms, or an aryl group haivng 6 to 8 carbon atoms and being substituted with a fluorine.
