Abstract

Provided is a metal-air battery and a method of using the same that make it possible to simplify replacement work while also sustaining high output effectively. The metal-air battery includes a cell unit provided with a plurality of metal-air battery cells in parallel, each metal-air battery cell being configured to include a metal electrode, an air electrode disposed facing the metal electrode, and a housing that supports the metal electrode and the air electrode. The metal-air battery also includes handles for example that act as a first replacing means enabling the replacement of the entire cell unit. With this arrangement, it is possible to simplify replacement work while also sustaining high output effectively.

Claims (10)

1. A metal-air battery comprising:

a cell unit provided with a plurality of metal-air battery cells in parallel, each metal-air battery cell being configured to include:

a metal electrode,

an air electrode disposed facing the metal electrode, and

a housing that supports the metal electrode and the air electrode; and

a power generation tank containing an electrolytic solution,

wherein a handle is further provided on a side of the cell unit, the handle enabling a replacement of the cell unit, and

wherein a through-hole is formed in each metal-air battery cell to supply the respective cells with electrolytic solution when the cell unit is immersed in the power generation tank, and to discharge externally from the cells into the power generation tank a product produced by a reaction of the metal electrodes and the air electrodes.

2. The metal-air battery according to claim 1 , wherein the handle is provided at a position higher than a surface height of the electrolytic solution when the cell unit is immersed.

3. The metal-air battery according to claim 1 , wherein the handle is provided with a finger-catching part on which a finger catches.
