The present invention relates to an electrolyte additive comprising a salt of an anion with K+ or Na+, the anion being derived from a nitrogen atom-containing compound, and a lithium-containing compound for forming a coating film. In addition, the present invention provides a lithium salt, a non-aqueous organic solvent, and the electrolyte additive. The present invention relates to a lithium secondary battery which includes a cathode employing a cathode active material, an anode employing an anode active material, a separator interposed between the cathode and the anode, and the non-aqueous electrolyte.
