Non Aqueous Electrolyte Containing Non Aqueous Electrolyte Additive, And Lithium Secondary Battery Including Same

Abstract: The present invention provides a non-aqueous electrolyte containing a non-aqueous electrolyte additive represented by chemical formula 1. In chemical formula 1, R1 and R2 are each independently selected from the group consisting of: H; F; a nitrile group; a thiocyanate group; an isothiocyanate group; an isocyanate group; a C1-10 alkoxycarbonyl group; a C1-10 alkylcarbonyl group; a sulfonyl group substituted with a C1-10 alkyl group, a C2-10 alkenyl group, or a C2-10 alkynyl group; an oxysulfonyl group substituted with a C1-10 alkyl group, a C2-10 alkenyl group, or a C2-10 alkynyl group; CF3; OCF3; COOCF3; and SO2CF3 (excluding the case in which both R1 and R2 are H), and R3 to R6 may each be independently selected from the group consisting of H, a C1-10 alkyl group, a C2-10 alkenyl group, a C2-10 alkynyl group, a C1-10 alkoxy group, a C3-12 cycloalkyl group, a C3-12 cycloalkenyl group, and a C6-20 aryl group.
