摘要： A non-aqueous electrolyte solution for a lithium secondary battery includes a lithium salt and an organic solvent. Based on 100 parts by weight of the non-aqueous electrolyte solution, the non-aqueous electrolyte solution includes 1 to 5 parts by weight of sultone compound having a carbon-carbon unsaturated bond in a cyclic structure; 1 to 5 parts by weight of cyclic carbonate compound with a vinyl group; 5 to 10 parts by weight of cyclic carbonate compound that is substituted with halogen; and 1 to 5 parts by weight of dinitrile compound. This non-aqueous electrolyte solution improves stability of a SEI film formed on a surface of an anode of a lithium secondary battery and thus improves normal temperature cycle performance and high temperature cycle performance.
