PURPOSE: Non-aqueous electrolyte for a lithium secondary battery is provided to maintain storage performance at high temperatures to be excellent, and to improve cycle performance. CONSTITUTION: Non-aqueous electrolyte for a lithium secondary battery comprise halogenated alkyl silane in chemical formula 1, and succinic anhydride, pentaerythritol, (meth)acrylic acid ester of dipentaerythritol, or mixtures thereof. In chemical formula 1, R1, R2, R3, and R4 is hydrogen, halogen, or C1-5 alkyl group independently. Among the R1, R2, R3, and R4, at least one is halogen, and at least one is a C1-5 alkyl group. |
