Abstract:
The present disclosure relates to a cathode for a lithium air battery and a method of manufacturing the same, and more particularly to a method of manufacturing a cathode for a lithium air battery, in which a hollow structure including a carbon material having a nitrogen functional group is synthesized through electrospinning of a thermally decomposable polymer, coating with a nitrogen-containing polymer and heat treatment, and is utilized without a binder as a cathode carbon material for a lithium air battery, thereby increasing the performance and lifespan of a lithium air battery.
