1. A non-aqueous electrolyte comprising an oxygen anion capturing compound, wherein the oxygen anion capturing compound is an oxazolidinone derivative in which an electron-withdrawing group is bound to the N-position thereof; and
wherein the oxazolidinone derivative is represented by Formula 1: where R is selected from the group consisting of —CN, —SO3H, —SO2R1, —NO2, —N+R24, —CO—R3, —CO—OR4, —CO—NR52, —F, —CL, —Br, and a hydrocarbon having 1 to 10 carbons, and R1, R2, R3, R4, and R5 are each independently hydrogen or an alkyl group of 1to 5 carbons, unsubstituted or substituted by —F, —Cl, —Br, —CN, or —NO2, wherein the hydrocarbon having 1 to 10 carbons is a compound whose hydrogen is partially or totally substituted by —NO2 or is a compound having 1 or 3 to 10 carbons and whose hydrogen is partially or totally substituted by —CN. |
