Non-aqueous electrolytic solution for lithium secondary battery and lithium secondary battery using the same

The invention provides a lithium secondary battery comprising a positive electrode, a negative electrode and a non-aqueous electrolytic solution comprising an electrolyte salt and a non-aqueous solvent comprising a chain carbonate and a cyclic carbonate selected from the group consisting of ethylene carbonate and propylene carbonate, characterized in that the non-aqueous electrolytic solution contains vinylene carbonate in an amount of 0.05 to 5 wt.% and an alkyne compound of formula (VI) in an amount of 0.1 to 3 wt.% in which formula each of R 25 to R 27 independently is a hydrogen atom or an alkyl group having 1 to 12 carbon atoms; x is 1; W is sulfinyl or oxalyl; and Y 6 is an alkyl group having 1 to 12 carbon atoms or an alkynyl group having 2 to 12 carbon atoms.
