Abstract

A non-aqueous electrolyte solution for a lithium secondary battery includes a lithium salt and an organic solvent. The non-aqueous electrolyte solution includes 0.5 to 5 weight% of vinylethylene carbonate and 0.1 to 5 weight% of 1,3-divinyltetramethyldisiloxane simul¬ taneously, based on the total weight of the non-aqueous electrolyte solution. 1,3-divinyltetramethyldisiloxane may significantly solve side effect of battery swelling without deteriorating effects such as improvement of performance deterioration and life cycle according to the addition of vinylethylene carbonate.
