Description

[Detailed Description of the Invention] The present invention relates to an improvement of an assembled battery formed by collecting a plurality of air batteries each having an air electrode on the side surface.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes an assembled battery case consisting of a bottomed case, and a heat insulating material 2 made of, for example, styrofoam is disposed on the inner bottom surface of the case. Reference numeral 3 denotes an air intake cylinder surrounded by the heat insulating material 2 except for the upper surface, and one end opening serving as the air intake port 3' is exposed from one side of the case 1, and the upper surface has an opening. Air discharge holes 3'' are bored at predetermined intervals.

Reference numeral 4 denotes an air battery having an air electrode 5 on the side surface, and a plurality of these are arranged on the upper surface of the cylinder 3 across the air discharge hole 3''.
is a case lid, which is spaced a little apart from the battery group and is provided with an air exhaust hole 6'.

Now, in the conventional battery structure of this type, as shown in FIG. The air flowing in passed through the gaps between the cells and was exhausted from the window on the other side.

However, with this structure, the unit cell is in direct contact with the atmosphere, so when the outside temperature is low, the battery itself will be cooled, and there is a concern that the battery performance will deteriorate.

On the other hand, according to the battery structure of the present invention, the air battery group is housed in a semi-sealed container consisting of an assembled battery case and a case lid, and the air is insulated from the upper surface as shown by the arrow in Figure 2. This is a type of convection phenomenon in which air is drawn into the air gap between the cells through the air intake cylinder, which is surrounded by all but one part, and is then exhausted from the air exhaust port after being warmed by the heat generated during discharge. Therefore, since air is supplied and discharged, even if the outside temperature is low, the air intake cylinder is surrounded by heat insulating material except for the top surface.
Once the battery is activated and generates heat, the heat insulating material retains that heat, raising the temperature of the air that is then introduced and supplying it to the battery group, which solves the problems with the conventional battery structure as described above. It is possible, and its practical value is great.
