1. A lithium-air battery comprising:
an anode comprising lithium metal or a lithium alloy;
a cathode configured to use oxygen as a cathode active material; and
an electrolyte layer between the cathode and the anode,
wherein the cathode comprises a mixed conductive layer,
wherein the mixed conductive layer comprises a core-shell structured particle comprising
a core portion comprising a solid electrolyte, and
a shell portion comprising an electronic conductor, and
wherein the mixed conductive layer has a porosity of about 5 percent to about 80 percent, and comprises a gas comprising oxygen contacting and in a pore of the mixed conductive layer, and
wherein the mixed conductive layer has an ionic conductivity of about 1.0×10−4 Siemens per centimeter or greater.
