Sulfone containing organic electrolyte for lithium-air battery having good energy efficiency and oxygen efficiency and lithium-air battery using the same

摘要

The present invention relates to an electrolyte for a lithium air battery containing a sulfone-based solvent having a high energy efficiency and excellent oxygen efficiency, and a lithium air battery using the same. More particularly, the present invention relates to a lithium- Lithium nitrate (LiNO ₃ ); And an electrolyte for a lithium air battery including an organic solvent, an amide solvent, a sulfoxide solvent, a sulfone solvent, an ether solvent, a nitrile solvent or a combination thereof, and a lithium air battery using the electrolyte. The lithium air battery according to the present invention has excellent oxidation stability and low volatility of a sulfone-based solvent, and is excellent in energy efficiency and oxygen efficiency due to lithium nitrate and an organic mixed solvent, .
