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.
