PURPOSE: A non-aqueous electrolytic solution is provided to form more stable solid electrolyte interface membrane on an electrode surface, thereby capable of restraining decomposition on an electrode surface, and to improve charging/discharging cycle life time of a battery. CONSTITUTION: A non-aqueous electrolytic solution comprises an ionizable lithium salt, an organic solvent, and silane compound in chemical formula 1. In chemical formula 1, R1, R2, R3, R4, R5, R6, R7, and R8 is respectively hydrogen, halogen, a vinyl group, a phenyl group, a benzyl group, a mercapto group, a C1-10 alkoxy group, a C3-18 cyclic alkyl group, a C3-8 cyclic epoxyalkyl group, or a substituted or unsubstituted C1-10 branched or linear alkyl group. |
