Abstract
The present disclosure relates to a positive electrode for lithium air batteries, a method of manufacturing the positive electrode, and a lithium air battery including the positive electrode, and more particularly to a positive electrode for lithium air batteries, wherein the positive electrode is manufactured through a dry process instead of a conventional wet process and a mixture of a positive electrode active material and a binder is ball-milled under specific conditions, thereby reducing or preventing a swelling phenomenon due to a solvent and increasing the force of coupling between the positive electrode active material and the binder, whereby it is possible to manufacture a high-density electrode and to improve the durability of the electrode, and wherein the lifespan of a lithium air battery is increased when the positive electrode is applied to the battery.
