Summary:The present invention relates a positive electrode for a lithium air battery, a lithium air battery comprising the same, and a method for manufacturing a positive electrode for a lithium air battery. Especially, in the present invention, the positive electrode for a lithium air battery comprises a carbon material supporting a catalyst formed of iron (Fe) derived from hemoglobin or an alloy thereof, and the catalyst can be used as a carrier for oxygen or carbon dioxide in the positive electrode for a lithium air battery, and therefore, the present invention has an advantage that efficiency of the battery can be increased. La présente invention concerne une électrode positive pour une batterie lithium-air, une batterie lithium-air comprenant celle-ci, et un procédé de fabrication d'une électrode positive pour une batterie lithium-air. En particulier, dans la présente invention, l'électrode positive pour une batterie lithium-air comprend un matériau carboné supportant un catalyseur formé de fer (Fe) dérivé de l'hémoglobine ou d'un alliage correspondant, et le catalyseur peut être utilisé en tant que support pour l'oxygène ou le dioxyde de carbone dans l'électrode positive pour une batterie lithium-air et, par conséquent, la présente invention a pour avantage que l'efficacité de la batterie peut être augmentée. 본 발명은 리튬 공기 전지용 양극, 이를 포함하는 리튬 공기 전지 및 리튬 공기 전지용 양극의 제조방법에 관한 것이다. 특히, 본 발명에서 리륨 공기 전지용 양극은 헤모글로빈으로부터 유래된 철(Fe) 또는 이의 합금으로 이루어진 촉매가 담지된 탄소재를 포함하고, 상기 촉매가 리튬 공기 전지용 양극에서 산소 또는 이산화탄소의 운반체로 사용될 수 있어, 본 발명은 전지의 효율을 높일 수 있는 이점이 있다.
