Abstract

There is provided an air battery including a first housings accommodating a base cell including a negative electrode, a positive electrode, and a separator disposed between the negative electrode and the positive electrode, and a second housing containing an electrolyte solution or water, in which the first housing and the negative electrode each have a hole leading to the separator, the second housing has a hole that is capable of being sealed, and the first housing and the second housing are disposed to face the hole of the first housing and the hole of the second housing each other.

First claim

The invention claimed is:

1. An air battery comprising:
a first housing configured to accommodate a base cell including a negative electrode, a positive electrode, and a separator disposed between the negative electrode and the positive electrode; and
a second housing configured to contain an electrolyte solution or water, wherein
the first housing and the negative electrode each have a hole leading to the separator,
the second housing has a hole that is capable of being sealed,
the first housing and the second housing are disposed in a state where the hole of the first housing and the hole of the second housing face each other,
the hole of the second housing, the first housing, and the negative electrode are aligned such that the electrolyte solution or water contained in the second housing can come into contact with the separator, and
the base cell is nested inside the first and second housing.

2. The air battery according to claim 1 , further comprising:
a sealing member configured to seal the hole of the second housing, wherein
when the sealing member is controlled to open the hole of the second housing, the electrolyte solution or water comes into contact with the separator via the hole of the first housing and the hole of the negative electrode to start power generation.

3. The air battery according to claim 1 , wherein
the second housing contains water, and
the separator includes an electrolyte.

4. An air battery comprising:
a base cell including a negative electrode, a positive electrode, and a separator disposed between the negative electrode and the positive electrode; and
an electrolyte solution or water contained in a separate chamber separated from the base cell in a housing accommodating the base cell, wherein
the negative electrode has a hole leading to the separator,
a partition member that separates the base cell from the electrolyte solution or water within the housing has a hole that is capable of being sealed,
the hole of the partition member is provided to face the hole of the negative electrode,
the hole of the partition member and the negative electrode are aligned such that the electrolyte solution or water contained in the second housing can come into contact with the separator, and
the base cell and the partition are nested inside the housing.

5. The air battery according to claim 4 , further comprising:
a sealing member configured to seal the hole of the partition member, wherein
when the sealing member is controlled to open the hole of the partition member, the electrolyte solution or water comes into contact with the separator via the hole to start power generation.

6. The air battery according to claim 4 , wherein
the separate chamber contains water, and
the separator includes an electrolyte.

7. The air battery according to claim 1 , wherein the negative electrode includes at least one selected from the group consisting of magnesium, zinc, aluminum, and iron.

8. A detection apparatus, comprising:
the air battery described in claim 1 ; and
a detector configured to detect power generation of the air battery.

9. The air battery according to claim 5 , wherein
the separate chamber contains water, and
the separator includes an electrolyte.

10. The air battery according to claim 4 , wherein the negative electrode includes at least one selected from the group consisting of magnesium, zinc, aluminum, and iron.

11. A detection apparatus, comprising:
the air battery described in claim 4 ; and
a detector configured to detect power generation of the air battery.
