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: An object is especially to provide a metal-air battery that ensures a high output and continuance of the output over a long period of time as compared with a conventional one. A metal-air battery in the present invention includes a case, air electrodes disposed on both sides of the case, and a plurality of metal electrodes disposed inwardly separately from the air electrodes. The metal electrodes are opposed to one another via a space (S). The metal-air battery of the present invention can inhibit the reaction product from depositing between the air electrode and the metal electrode. A degree of freedom of a distance between the air electrode and the metal electrode is high. As described above, the high output and the continuance of the output over a long period of time are ensured.
