Abstract
An organic electrolyte solution and a lithium battery using the same are provided. The organic electrolyte solution uses a monomer compound which can be electrografted, and which prevents crack formation caused by volumetric changes in the anode active material during battery charging/discharging. This improves charge/discharge characteristics, thereby improving the stability, reliability, and charge/discharge efficiency of the battery.
