Perovskite-type oxide catalyst-based carbon electrodes were studied as air electrodes for aqueous lithium-air secondary batteries, which were comprised of a carbon black air electrode with La 0.8 Sr 0.2 Fe 0.8 Mn 0.2 O 3 catalyst, an aqueous electrolyte solution of saturated LiOH with 10 M LiCl, and a water-stable lithium electrode. The oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) benefited from the expanded surface area of La 0.8 Sr 0.2 Fe 0.8 Mn 0.2 O 3 during charge
