摘要：
A cathode configured to use oxygen as a cathode active material, the cathode including: a porous film, wherein the porous film includes a metal oxide, and wherein a surface of the porous film has root mean square (RMS) roughness (Rq) of about 0.01 micrometer to about 1 micrometer, and a porosity of the porous film is about 50 volume percent to about 99 volume percent, based on a total volume of the porous film.
