Abstract
A battery device, including a negative electrode; an air electrode; and an electrolyte layer that is provided between the negative electrode and the air electrode, where the air electrode includes a plurality of portions having discharge over-voltages that are different between each portion in a direction from the negative electrode to the air electrode, and where a discharge over-voltage of a portion of the air electrode closest to the negative electrode is lower than a discharge over-voltage of the other of the plurality of portions
