Electrolyte for lithium air batteries, and lithium air battery using the same

An electrolyte for lithium air batteries containing:

• an organic solvent that is a phosphoric acid ester and/or phosphonic acid ester, and lithium nitrate, characterized in that:
• a concentration of the lithium nitrate in the organic solvent satisfies a range of 2 mol/L to 5.5 mol/L inclusive, and
• the phosphoric acid ester is represented by the following chemical formula (1), and the phosphonic acid ester is represented by the following chemical formula (2):
• where R1, R2 and R3 are each independently a group selected from the group consisting of a linear alkyl group having one to three carbon atoms, a linear alkenyl group having two or three carbon atoms, an alkynyl group having two or three carbon atoms, and a derivative thereof.
