Abstract: The present invention relates to a cathode catalyst for a metal-air battery, a method for manufacturing the same, and a metal-air battery comprising the same. More specifically, the present invention relates to a cathode catalyst for a metal-air battery, a method for manufacturing the same, and a metal-air battery comprising the same having an improved storage capacity for charging/discharging and an increased charge-discharge cycle lifetime. The cathode catalyst is characterized by having a layered perovskite structure, and including lanthanum and nickel oxides. The cathode catalyst including the layered perovskite is used for manufacturing a cathode for a metal-air battery, and a metal-air battery is provided using the same. As a result, the charge-discharge polarisation of the metal-air battery is decreased, the storage capacity is increased, and the charge-discharge cycle lifetime can be improved.

Abstract: The present invention relates to a cathode for a metal-air battery, a method for manufacturing the same, and a metal-air battery including the same. The cathode comprises a needle-shaped core including two or more species of metals selected from the group consisting of nickel, cobalt, manganese, zinc, iron, copper, and chrome, or a cobalt oxide; and a flake-shaped shell including an oxide containing two or more species of metals selected from the group consisting of nickel, cobalt, manganese, zinc, iron, copper, and chrome or a cobalt oxide. As such, the core-shell structure may lead to a reduction in the charge voltage of the metal-air battery as well as the taking of the good capacity characteristics of the transition metal oxide. Further, according to the present invention, the cathode for a metal-air battery may be produced without adding carbon or binder.
