Lithium-air battery and and method for manufacturing same

摘要

Preparing a titanium dioxide (TiO ₂ ) and ruthenium (Ru) precursor; adding titanium dioxide and the ruthenium precursor to a solvent to produce a first solution; adding a basic material to the first solution, Preparing a second solution in which the ruthenium precursor is dissolved, mechanically mixing the second solution to produce a titanium dioxide-ruthenium hydroxide complex in the second solution, Titanium dioxide-ruthenium hydroxide complex; subjecting the titanium dioxide-ruthenium hydroxide complex to a thermal treatment to produce the titanium dioxide-ruthenium hydroxide complex oxidized titanium dioxide-ruthenium oxide complex; Titanium-ruthenium oxide composite is coated on a current collector to form a positive electrode active material A manufacturing method of a lithium air battery comprising, can be provided.
