Abstract: Provided are a novel metal catalyst for preparing cyclic carbonate, and a method for preparing cyclic carbonate using the same, and more particularly, a method for selectively preparing cyclic carbonate in a high yield and at a higher conversion rate as compared to the existing catalysts, using the metal complex including a ligand represented by Chemical Formula 1 below and a trivalent metal in Group 8 or Group 13 as a catalyst and using various structures of epoxide compounds and carbon dioxide as raw materials. In addition, provided are the prepared cyclic carbonate, and an electrolyte including the same: in Chemical Formula 1, R1 is hydrogen, (C1-C20)alkyl or halogen; R2 is hydrogen, (C1-C20)alkyl, (C1-C20)alkoxy, halogen or nitro.
