Abstract
The present invention relates to a positive electrode of a lithium-air battery having a side reaction prevention layer with a partially introduced metal catalyst, and a method for preparing the same, and in particular, to a positive electrode of a lithium-air battery having a side reaction prevention layer with a metal catalyst sporadically partially introduced to a surface thereof, and a method for preparing the same. The lithium-air battery according to the present invention suppresses a side reaction at an interface between a positive electrode active material and an electrolyte thereby effectively reduces an overvoltage when charged, and therefore, does not cause liquid electrolyte decomposition, which is effective in enhancing a cycle life.
