摘要： Disclosed is an electrode for lithium-air batteries without using a binder and a carbon additive and a method of manufacturing the same, and more specifically, provided is a nanofiber network-based current collector-catalyst monolithic porous air electrode which has an improved specific surface area and high air permeability as the energy density per weight is increased and the diameter, porosity, and thickness of the nanofibers are controlled by utilizing a significantly light polymer and carbon based material.

摘要： A lithium-air battery catalyst having a 1D polycrystalline tubes structure of a ruthenium oxide-manganese oxide complex includes the ruthenium oxide-manganese oxide complex having at least one polycrystalline tubes structure among a core fiber-shell patterned nanotubes structure and a double walls patterned composite double tubes structure, and the ruthenium oxide-manganese oxide complex is formed as an air electrode catalyst.
