摘要
The present invention has for its object to provide a non-aqueous electrolyte for lithium air batteries capable of simultaneously holding back positive electrode overvoltage, reactions of the negative electrode with the electrolyte and dendrite growth during charging thereby making an improvement in the output performance, and a lithium air battery using the same. The invention provides a non-aqueous electrolyte for lithium air batteries, containing an organic solvent and a lithium salt. The lithium salt contains at least LiX (where X stands for Br and/or I) and lithium nitrate. The molar concentration (mol/L) of LiX in the non-aqueous electrolyte satisfies a range of no less than 0.005 to no greater than 2.0, and the molar concentration (mol/L) of the lithium nitrate in the non-aqueous electrolyte satisfies a range of greater than 0.1 to no greater than 2.0.
