摘要： The present invention provides a metal-air cell that allows pieces of an electrode active material that have fallen off to contribute to a discharge reaction and thus has high power generation efficiency.The metal-air cell according to the present invention includes an electrolyte cell containing an electrolyte, a metal electrode disposed in the electrolyte cell and serving as an anode, and an air electrode serving as a cathode. The metal electrode includes a current collector and an electrode active material part disposed on the current collector and made of an electrode active material. The current collector includes a supporting part supporting the electrode active material part and a receiving part disposed between a bottom of the electrolyte cell and the electrode active material part. The receiving part includes a projection projecting in the electrolyte cell beyond a side surface of the electrode active material part toward a sidewall of the electrolyte cell.

摘要： The present invention has been achieved to provide a metal-air battery that allows removal of a metallic compound without suspending power supply. The metal-air battery of the present invention includes: first and second electrolytic tanks for storing an electrolytic solution; a metallic electrode to serve as an anode provided in the first electrolytic tank; and an air electrode to serve as a cathode, wherein the metallic electrode is formed of a metal which becomes a metallic ion or composes a metallic compound in the electrolytic solution with progress of a battery reaction, the first and second electrolytic tanks are communicated with each other for allowing the electrolytic solution in the first electrolytic tank to move into the second electrolytic tank, and the metallic ion or the metallic compound in the electrolytic solution is precipitated as a metallic compound precipitate in the second electrolytic tank.
