    摘要: Disclosed is a compound represented by the following formula 1: wherein, each of R1˜R13 independently represents —H, —F, —Cl, —Br, —I, —OH, —SH, —COOH, —PO3H2, —NH2, —NO2, —O(CH2CH2O)nH (wherein, n is an integer of 1˜5), C1˜C12 alkyl group, C1˜C12 aminoalkyl group, C1˜C12 hydroxyalkyl group, C1˜C12 haloalkyl group, C2˜C12 alkenyl group, C1˜C12 alkoxy group, C1˜C12 alkylamino group, C1˜C12 dialkylamino group, C6˜C18 aryl group, C6˜C18 aminoaryl group, C6˜C18 hydroxyaryl group, C6˜C18 haloaryl group, C7˜C18 benzyl group, C7˜C18 aminobenzyl group, C7˜C18 hydroxybenzyl group, C7˜C18 halobenzyl group, or nitrile group (—CN); and at least one of R4˜R13 is nitrile group (—CN). A non-aqueous electrolyte comprising: (i) a lithium salt, (ii) a solvent, and (iii) a compound represented by formula 1; and a secondary battery comprising the non-aqueous electrolyte are also disclosed. When the compound represented by formula 1 is added to a non-aqueous electrolyte, it is possible to improve the safety of a secondary battery in an overcharged state.
