Patent ID: 8906546

Claim:
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, —SO 3 H, —SO 2 R 1 , —NO 2 , —N + R 2 4 , —CO—R 3 , —CO—OR 4 , —CO—NR 5 2 , —F, —CL, —Br, and a hydrocarbon having 1 to 10 carbons, and R 1 , R 2 , R 3 , R 4 , and R 5 are each independently hydrogen or an alkyl group of 1to 5 carbons, unsubstituted or substituted by —F, —Cl, —Br, —CN, or —NO 2 , wherein the hydrocarbon having 1 to 10 carbons is a compound whose hydrogen is partially or totally substituted by —NO 2 or is a compound having 1 or 3 to 10 carbons and whose hydrogen is partially or totally substituted by —CN.
