ABSTRACT:
A nonaqueous electrolytic solution and a lithium battery employing the same include a lithium salt, an organic solvent, and a halogenated benzene compound. The use of the nonaqueous electrolytic solution causes formation of a polymer by oxidative decomposition of the electrolytic solution even if a sharp voltage increase occurs due to overcharging of the battery, leading to consumption of an overcharge current, thus protecting the battery.
