摘要： An active material layer of a metal negative electrode includes: active material particles including a negative active material; and an additive having particles larger in average particle size than the active material particles. The metal negative electrode is immersed in an alkaline aqueous solution, and the additive is eluted into the alkaline aqueous solution. In a place where the additive is previously found, a space is defined in the active material layer.

摘要： A method for producing an air electrode includes a kneading step of kneading an oxygen reduction catalyst, a conductive auxiliary agent, and a water-repellent resin (binder) in a water solvent; and a rolling step of rolling with a roller the kneaded product produced in the kneading step. The rolling step includes rolling the kneaded product with the roller several times in many directions (at least two or more different rolling directions). In the formed air electrode, the water-repellent resin is fiberized in the air electrode, and the fibers thereof are oriented in many directions to form a netlike shape.

摘要： A metal-air battery includes a metal negative electrode (12), an oxygen-generating electrode placed on a surface of the metal negative electrode, and an air electrode placed on another surface of the metal negative electrode. The metal negative electrode includes at least a negative electrode active material layer facing the oxygen-generating electrode. A first separator placed in contact with the negative electrode active material layer is placed between the negative electrode active material layer and the oxygen-generating electrode.
