1. A method of manufacturing an electrolyte membrane for a lithium-air battery, comprising:
preparing an inorganic salt;
preparing an inorganic melt admixture comprising the inorganic salt;
immersing a separator in the inorganic melt admixture; and
drying the immersed separator,
wherein the inorganic salt comprises:
three types of nitrogen-oxide compounds, four types of nitrogen-oxide compounds, or five types of nitrogen-oxide compounds,
wherein the three types of the nitrogen-oxide compounds comprise an amount of about 29 mol % to 35 mol % of lithium nitrate, an amount of about 51 mol % to 56 mol % of potassium nitrite and an amount of about 10 mol % to 15 mol % of cesium nitrate,
the four types of the nitrogen-oxide compounds comprise an amount of about 27 mol % to 31 mol % of lithium nitrate, an amount of about 38 mol % to 50 mol % of potassium nitrate, an amount of about 11 mol % to 20 mol % of sodium nitrate and an amount of about 10 mol % to 13 mol % of calcium nitrate, and
the five types of the nitrogen-oxide compounds comprise an amount of about 14 mol % to 17 mol % of lithium nitrate, an amount of about 29 mol % to 31 mol % of potassium nitrate, an amount of about 28 mol % to 32 mol % of cesium nitrate, an amount of about 9 mol % to 11 mol % of sodium nitrate and an amount of about 13 mol % to 18 mol % of calcium nitrate,
all the mol % based on the total mole of the nitrogen-oxide compounds.
