  • Patent number: 10763559
    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.

  • Publication number: 20190372086
    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.

  • Patent number: 10411226
    Abstract: It is an object to provide a metal-air battery capable of, in particular, properly discharging produced gas externally, and performing rapid water supply. A metal-air battery according to the present invention is characterized by including a unit body including a plurality of metal-air battery cells; a water supply space provided on a top surface of the unit body and is common to the metal-air battery cells; and a wiring opening which communicably connects with the water supply space and from which wires connected to electrodes of the metal-air battery cells are drawn out. A tubular portion having the wiring opening projects from the top surface of the unit body.

  • Publication number: 20180053945
    Abstract: An object of the present invention is to provide a metal-air battery capable of achieving high enough output (maximum power) to be applicable to use such as charging a cell phone. The metal-air battery of the present invention uses a metal as an active material of a negative electrode 30 and oxygen in the air as an active material of a positive electrode 20. The positive electrode 20 comprises a current collector 21 composed of a plate-like porous metal material and a conductive material layer 23 disposed on one surface side of the current collector 21. At least one surface of the current collector 21 on which the conductive material layer 23 is disposed is coated with a conductive coating material to form a coating conductive film 25.
