Claim:
1. A lithium air battery comprising: a negative electrode; a lithium ion conductive solid electrolyte membrane; and a positive electrode using oxygen as a positive electrode active material, wherein a first electrolyte comprising lithium ion conductive polymers having a weight average molecular weight greater than 2000 grams per mole, compounds represented by Formula 1 below, and lithium salts are included between the lithium ion conductive solid electrolyte membrane and the positive electrode: wherein R R n is in a range of 1 to 20, wherein the amount of the lithium ion conductive polymers is in a range of about 1 to about 90 parts by weight based on 100 parts by weight of the compounds of Formula 1 in the electrolyte; and the lithium ion conductive polymer is one or more polymers selected from the group consisting of polypropylene oxide, polyethylene oxide, polyethylene oxide/polypropylene oxide copolymer.
