The present invention relates to a positive electrode for a metal-air battery, a method of manufacturing the same, and a metal-air battery including the same. The metal-air battery includes a needle-like shape and is made of cobalt oxide or nickel, cobalt, manganese, zinc, iron, copper, A core comprising an oxide containing at least two metals selected; And a shell comprising an oxide containing at least two metals selected from the group consisting of cobalt oxide or nickel, cobalt, manganese, zinc, iron, copper and chromium. In this way, the core-shell structure not only allows the excellent capacity characteristics of the transition metal oxide to be obtained, but also the charge voltage of the metal-air battery can be lowered. In addition, the positive electrode for a metal-air battery according to the present invention can be produced without containing carbon and a binder. |
