The present invention lithium-relates to an air cell electrode and a method of manufacturing the same, more specifically, by using a very light material the nanofiber network without a binder, and the conductive material used to increase the energy density per weight, the diameter of the nanofibers, porosity and the thickness is controlled specific surface area and the air permeability is improved nanofiber network-based current collector - catalyst provides for an integral porous air electrode.
If the individual nano fibers constituting the nanofiber network having a fabric-like structure are non-conductive material, the porous air electrode, that is single-layered core (non-conductive nano fibers) / shell (a first containing a conductive catalyst layer uniformly coated on the surface conductive catalyst layer) structure to provide or, individual nanofibres of surface to uniformly continuously coating the first coating layer (conductive layer) and the second coating layer (catalyst layer) at the same time include a laminated porous air electrode, that is, the core (non-conductive nano fibers) and / shell provides a (first conductive layer / the second catalyst layer) structure. In addition, if the individual nanofibers are conductive carbon nano fibers constituting the nanofiber network having a fabric-like structure, a porous air electrode, that is single-layered core (conductive carbon nanofiber) comprises a conductive catalyst layer or catalyst layer uniformly coated on the surface / providing a shell (first conductive catalyst layer) naejineun single-layered core (conductive carbon nanofiber) / shell (first catalyst layer) structure.
These nano-stacked fiber layered network electrode, or may have as many reaction area (reaction site) in a single size through the laminated structure to be superimposed, or roll formed to each other, excellent electrical conductivity, smooth air and the movement of the lithium ions, body a suitable current density and improved stability, and a large area at low cost, mass production of lithium having a layered structure as possible - has the effect of providing an air electrode nanofiber network and a method of manufacturing the electrode for air battery.
