Description
【発明の詳細な説明】 本発明はボタン型空気電池の製造法に関するものであ
る。The present invention relates to a method for manufacturing a button type air battery.
従来この種のボタン型空気電池は、正極に活性炭もしく
は活性炭に酸化還元能力を有する無機もしくは有機化合
物を含有させたものを、保持体で保持して空気極として
用い、空気中の酸素を吸着し、イオン化することにより
電流を取り出していた。Conventionally, in this type of button-type air battery, a positive electrode containing activated carbon or an activated carbon containing an inorganic or organic compound having a redox capacity is used as an air electrode by holding it on a holder to adsorb oxygen in the air. , The current was taken out by ionization.
しかし、このボタン型空気電池は、正極缶の底面が電池
の出力端子を兼ねているため、多くの使用機器は、電池
収納ケースの端子板が挿入電池の正極缶の底面に直接接
触するような構造になつている。However, in this button type air battery, the bottom surface of the positive electrode can also serves as the output terminal of the battery, so in many devices, the terminal plate of the battery storage case is in direct contact with the bottom surface of the positive electrode can of the inserted battery. It is structured.
このため使用機器の端子板が幅広の板状の場合は、正極
缶に設けてある空気流入孔の入口が遮蔽されてしまい、
空気の流入が妨げられて酸素の供給が不足し、空気極の
作動が不活発になる欠点を有していた。Therefore, when the terminal plate of the device used is a wide plate, the inlet of the air inflow hole provided in the positive electrode can is blocked,
There is a drawback that the inflow of air is hindered and the supply of oxygen becomes insufficient, so that the operation of the air electrode becomes inactive.
これを改善するため空気流入孔を有する正極缶の底面を
外方に向つて平面状に突出させると共に空気極も正極缶
底面形状に類似させて変形させた電池が開発され、また
特開昭５０−１０８５２９号公報のように予め半円状に
突出した正極缶底面と空気極とを用いた空気電池もあっ
たが、空気極の変形により酸素のイオン化能力の劣化が
大きく放電特性の劣化、またはクリーピング特性の悪化
をもたらす等の欠点を有していた。In order to improve this, a battery has been developed in which the bottom surface of a positive electrode can having an air inflow hole is projected outwardly in a plane shape, and the air electrode is also deformed in a shape similar to the bottom surface of the positive electrode can. Although there is an air battery using a positive electrode can bottom surface and an air electrode which are protruded in a semicircular shape in advance as in Japanese Patent No. 108529, the deterioration of the ionization ability of oxygen is largely caused by the deformation of the air electrode, and the discharge characteristics are deteriorated. It had a defect that the creeping property was deteriorated.
本発明は空気極を平板状に保持し、正極缶の底面を断面
半円状とすると共に空気流入孔を底面の中心部分を除い
て断面外向きに形成することで、使用時に適量な空気を
供給しつつ放電特性、クリーピング特性を向上させるこ
とを目的とする。The present invention holds the air electrode in a flat plate shape, makes the bottom surface of the positive electrode can have a semicircular cross section, and forms the air inflow hole outward in cross section except for the central portion of the bottom surface, so that an appropriate amount of air can be generated during use. The purpose is to improve discharge characteristics and creeping characteristics while supplying.
本発明によつてなる空気電池を図面により説明する。An air battery according to the present invention will be described with reference to the drawings.

と同時に、クリンプ下型で正極缶１の外方に平面状に突
出した底面２を、外方に向って断面半円状に成形する。Reference numeral 1 denotes a positive electrode can that also serves as a positive electrode terminal. A bottom surface 2 has a semicircular cross section, and a proper number of air inflow holes 3 are formed outside the central portion of the bottom surface 2 in a cross section outward. An air electrode 4 is formed without deformation and is in contact with the hydrophilic semipermeable membrane 5. Reference numeral 6 denotes an electrolytic solution holder holding a caustic alkaline electrolyte, which is a non-woven fabric or a porous body having excellent liquid retention and liquid resistance, and is in contact with the negative electrode body 7. 8 is a non-woven fabric,
In the space 12 between the water-repellent polytetrafluoroethylene sheet 9 having a large number of micropores in contact with the air electrode 4 and the bottom surface 2 of the positive electrode can 1 in which the air inflow hole 3 is provided, It has a function of retaining and uniformly supplies air to the air electrode 4. Reference numeral 10 denotes a negative electrode can, and a positive electrode can 1 through a gasket 11.
The opening is bent inward and crimped to seal it. This crimp lower mold is concavely processed into a semicircular cross section while leaving an annular flat portion in the recording, and the peripheral edge of the air electrode 4 is pressed by the annular flat portion to hold the air electrode 4 in a flat shape without deforming it. At the same time as bending the opening of the positive electrode can 1 with the crimp upper mold, the bottom face 2 protruding in a planar shape outward of the positive can 1 with the crimp lower mold is shaped to have a semicircular cross section toward the outside.
本発明のボタン型空気電池の空気流入孔は正極缶１の底
面２が断面半円状に凸状で、空気流入孔が底面２の中心
からはずれた場所に断面外向きに形成されている。The air inlet of the button type air battery of the present invention has a convex bottom surface 2 of the positive electrode can 1 having a semicircular cross section, and the air inlet hole is formed outward at the location off the center of the bottom surface 2.
このため、使用機器の電池収納ケースの通常接触端子板
に対して、隙間が形成され、空気流入孔の入口は遮蔽さ
れることはなく、空気が流入し適量な空気が均一に供給
される。For this reason, a gap is formed with respect to the normal contact terminal plate of the battery housing case of the device used, the air inlet is not blocked, and air flows in and an appropriate amount of air is uniformly supplied.
また空気極自体は変形がなく、空気極の微細な割れやク
ラツクがなく加えて底面内側に空間部12を有しているた
め、クリーピング特性の向上と急速放電性能の向上が得
られる。Further, since the air electrode itself is not deformed, and the air electrode does not have fine cracks or cracks and has the space portion 12 inside the bottom surface, it is possible to improve creeping characteristics and rapid discharge performance.

生もなくなり表の結果が出たものである。This is because the space does not block the outward air inflow hole and acts as an air stopper, so that the required amount can be uniformly supplied to the air electrode and there is no deformation of the air electrode, and cracks and cracks do not occur. It is the result of disappearing table.
