POSITIVE ELECTRODE CATALYST FOR LITHIUM-AIR SECONDARY BATTERY, METHOD FOR MANUFACTURING SAME, AND LITHIUM-AIR SECONDARY BATTERY COMPRISING SAME

摘要

Disclosed are a positive electrode catalyst for a lithium-air secondary battery, a method for manufacturing the same, and a lithium-air secondary battery comprising the same. An embodiment of the present invention provides a method for manufacturing a positive electrode catalyst for a lithium-air secondary battery, the method comprising the steps of: forming a first solution by adding a titanium ion precursor to a solvent, followed by stirring; forming a second solution by adding an organic material to a solvent, followed by stirring; forming a nanofiber composite by mixing the first solution and the second solution and then spinning the mixed solution; and forming titanium oxide (Ti02) nanofibers by thermally treating the nanofiber composite.
