PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte characterized by including an organic solvent, lithium salt, and a biphenylene oxide compound in regard to the nonaqueous electrolyte superior in overcharge safety and a lithium battery adopting this nonaqueous electrolyte. SOLUTION: Since this nonaqueous electrolyte protects the battery by consuming an overcharge current by forming a polymerization material through oxidizing and decomposing the electrolyte even if voltage increases when the battery is overcharged by various causes, a swelling phenomenon reduces while the overcharge safety is improved, and a high temperature characteristic, standard capacity, and a service life characteristic can be improved so that the nonaqueous electrolyte is usefully used for the lithium battery. |
