An organic electrolytic solution and a lithium secondary battery employing the same, wherein the organic electrolytic solution for a lithium secondary battery includes a polymer adsorbent having an ethylene oxide chain capable of being adsorbed into a lithium metal, a material capable of reacting with lithium to form a lithium alloy, a lithium salt, and an organic solvent. The organic electrolytic solution may be applied to all types of batteries including lithium ion batteries, lithium polymer batteries and lithium metal polymer batteries using a lithium metal for a negative electrode material, and the like. In particular, when the organic electrolytic solution is utilized in a lithium metal polymer battery, it serves to stabilize the lithium metal, and to increase the lithium ionic conductivity, thereby improving the cycle characteristics and charging/discharging efficiency of the battery.
