<P>PROBLEM TO BE SOLVED: To provide an air electrode equipped with a dual function of oxygen generation and oxygen reduction as well as a gaseous diffusion property, with small polarization at oxygen reduction and having a high durability against oxygen generation/reduction cycle, as well as an air secondary battery of a simple structure enabling charging and discharging with a cathode and an anode alone, with high energy density, high output density, and high durability, and moreover, capable of realizing a larger capacity through lamination. <P>SOLUTION: The air electrode 1 is made by mixing nickel powder, pyrochlore type oxide containing iridium, and a binder. The air secondary battery is provided with this air electrode 1 as a cathode, and an anode 2 with either zinc, iron, aluminum, or hydrogen as an active material. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
