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.
Claims8
An organic electrolyte solution comprising:
- a lithium salt;
- an organic solvent comprising a high dielectric constant solvent and a low boiling point solvent;
- and
- a monomer compound represented by Formulae 6-9:
- wherein the monomer compound is present in an amount ranging from about 0.5 to about 20 wt % based on the total weight of the organic solvent.
