Abstract
The present invention relates to a lithium air battery and a method of manufacturing the same, wherein the lithium air battery comprises; a positive electrode which uses oxygen as an anode active material and is formed by laminating carbon black secondary particles which are composed of carbon black primary particles and graphene, and including macropores having a pore size range of exceeding 100 nm formed between the carbon black secondary particles; a negative electrode disposed to face the positive electrode; and a separation membrane disposed between the positive electrode and the negative electrode. The lithium air battery provides an increase in discharge capacity in a discharge test and a decrease in overvoltage, and can be manufactured by a simple method.
