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.
