Abstract: A metal-air battery is comprised by a metal-air battery unit having a plurality of juxtaposed metal-air battery cells with a small number of components and a simple structure for injection of the electrolytic solution into each cell. Each metal-air battery cell has an air electrode, a metal electrode arranged to face the air electrode, and a casing configured to support the air electrode and the metal electrode. Each casing includes an air chamber and a liquid chamber. Each air chamber has an upper part opened to the outside. The casing has a liquid feeding port communicating with the liquid chamber for admitting an electrolytic solution when the metal-air battery unit is lowered into a container of electrolytic solution.

Abstract: It is an object to provide a metal-air battery and a method for removing an oxide film that can appropriately remove an oxide film while reducing waste of power required for removing the oxide film. The metal-air battery of the present invention includes a battery main body portion in which a metal electrode and an air electrode are arranged so as to be opposed to each other through an electrolytic solution, a USB terminal to which an external load is connected, and a controller for electrically connecting the battery main body portion and the USB terminal, the controller includes a microcomputer for determining connection or disconnection of an external load to or from the USB terminal, and when the microcomputer confirms the connection of the external load, a current for removing an oxide film is made to flow through a circuit including the metal electrode, the air electrode, and an oxide film removing resistor.
