ELECTROLYTE SOLUTION FOR LITHIUM AIR BATTERIES, AND LITHIUM AIR BATTERY

The present invention aims to provide an electrolyte solution for a lithium-air cell, the electrolyte solution having excellent chemical stability and a high withstand voltage and being in a stable liquid state without undergoing precipitation of salts or coagulation over a broad temperature range. The present invention also aims to provide a lithium-air cell which is produced using the electrolyte solution for a lithium-air cell and has excellent long-term reliability and good charge-discharge cycle characteristics. The present invention relates to an electrolyte solution for a lithium-air cell, the electrolyte solution containing: an organic solvent that contains a chain alkyl sulfone compound represented by Formula (1): wherein R 1 and R 2 independently represent a straight-chain or branched-chain alkyl group containing 1 to 4 carbons and may be the same as or different from each other; and a lithium salt.
