PURPOSE: Provided are an organic electrolyte containing monomers for forming polymers to trap a mixed organic solvent and lithium salts, which dose not volatilized at a high temperature, and a lithium secondary battery using the organic electrolyte. CONSTITUTION: The organic electrolyte comprises the mixed organic solvent, the lithium salts, 1-20wt%(based on the total weight of the organic electrolyte) of the monomers polymerized at 40-150deg.C for forming the polymers to trap the mixed organic solvent and the lithium salts, and 0.01-2wt%(based on the total weight of the organic electrolyte) of a polymerization initiator selected from the group consisting of benzoyl peroxide, acetyl peroxide, lauroyl peroxide, and azobis isobutyronitrile, wherein the monomer is acrylonitrile, methyl acrylate, methacrylate, methyl methacrylate, and a mixture thereof. And the lithium secondary battery comprises a cathode containing lithium-contained metal oxides, an anode containing metal lithium, lithium alloy, or carbon material, a separator laid between the cathode and the anode, and the organic electrolyte. |
