In devices designed to remove batteries, the direction in which the batteries are inserted must be specified, and the batteries must be set correctly to avoid misunderstanding the polarity of the batteries.

裏の見分けがつき難い欠点がある。However, when this conventional battery is used in a hearing aid or the like, the hearing aid is extremely small, so there is a drawback that it is difficult to replace the battery into the battery storage chamber without making a mistake. Furthermore, button-type air batteries often used in hearing aids have convex top and bottom surfaces, making it difficult to distinguish between the front and back. In particular, PR536 with an outer diameter of 5.8 mm and a height of 3.6 mm and an outer diameter of 7.
A small battery such as the PR41, which is 9 mm long and 3.6 mm high, has the disadvantage that it is difficult to distinguish between the front and the back.

It has a. A diffusion paper 3a, a water-repellent film 4a, an air electrode 5a which is a power generation element serving as a positive electrode, a separator 6a, and an impregnating material 7a are sequentially placed on this positive electrode can 1a. This air electrode 5a is electrically connected to the positive electrode can 1a at this outer peripheral portion. Further, the number of air intake holes 5a, the size and shape of the holes, etc. can be selected as appropriate depending on the use of the battery.

After the positive electrode can 1a and the gasket 8a are integrated in this manner, the positive electrode can 1a and the gasket 8a are inserted into the negative electrode can 9, and only the top 9a of the negative electrode can 9 is caulked. Next, after the negative electrode mixture 10a is filled, the current collector 11 is placed. This current collector 11 is shown in FIGS.
), the central portion is a porous portion 11a. FIGS. 2A and 2B are a plan view and a cross-sectional view, respectively, showing one embodiment of a current collector according to the present invention. This current collector 11 has a porous portion 11a in the center, and its outer diameter is the same as or slightly larger than the inner diameter of the negative electrode can 9. This porous portion 11a is provided with micropores by punching. Due to this porous portion 11a, the negative electrode mixtures 10 disposed on both sides perform the same electrochemical reaction, and are also continuous in terms of electronic conductivity. The outer periphery of this current collector 11 is the negative electrode can 9
is in contact with and electrically connected.

なる。Further, the reason why the porous portion 11a is provided only in the center of the current collector 11 is that the outer circumferential portion of the current collector 11 is compressed between the gaskets 8 and the alkaline electrolyte leaks out. This is to prevent If the entire surface of the current collector 11 is porous, the alkaline electrolyte will permeate to the outer periphery of the current collector 11 and easily leak out to the outside of the battery.

。Finally, the opening in the bottom 9b of the negative electrode can 9 is caulked to completely seal the battery. When this battery is used in a device as shown in FIG. 3, air is taken into the battery through the air intake hole 2 of the positive electrode can 1. This air is spread through the diffusion paper 3 over the entire surface of the water-repellent film 4 made of a microporous film. This infiltrated and diffused air passes through the water-repellent film 4, and only oxygen gas is used as a positive electrode active material at the air electrode 5.

At 4V, the nominal capacity is 100 mAH, which is approximately 1.7 times larger than the nominal capacity of a hearing aid mercury battery of the same size, 60 mAH. Further, when both the positive electrodes are used in common, the reaction area of the air electrode 5 is twice that of a conventional air battery, so the discharge current is twice as large. That is, compared to conventional batteries, it can be used with twice as much current, and can also be used in hearing aids for people with moderate to severe hearing loss. In this example, continuous discharge at 10 mAH was possible.

Equipment can be operated normally. Furthermore, since the present invention has a battery structure in which the electrode reaction area is twice as large as that of conventional batteries, it is possible to provide a battery that can extract a large current.
