    • Provided are a positive electrode for a lithium air battery, a method for manufacturing the same, and a lithium air battery including the same. The positive electrode for a lithium air battery includes oxygen that is used as a positive electrode active material, an oxidation reduction catalyst for oxygen, and a matrix for carrying the catalyst, and minimizes a side reaction against an organic electrolyte by using a porous graphene matrix as the matrix and a transition metal oxide nanowire arranged on the porous graphene matrix as the catalyst, so that battery life can be expanded. In addition, a uniform catalyst growth is possible on the matrix to improve electrical characteristics, and thus battery performance can be improved. In addition, the method for manufacturing a positive electrode for a lithium air battery can fix a catalyst on a matrix without a separate binder by including a step for manufacturing a porous graphene matrix and a step for directly growing a catalyst on the porous graphene matrix.
