Abstract
A porous carbonaceous composite material, a positive electrode and lithium air battery including the porous carbonaceous composite material, and a method of preparing the porous carbonaceous composite material. The porous carbonaceous composite material includes a carbon nanotube (CNT); and a modified carbonaceous material doped with a heterogeneous element, wherein the ratio of the number of surface oxygen atoms to the number of surface carbon atoms ranges upward from about 2 atom %.
