る。As is well known, alkaline batteries generate a small amount of gas during discharge or storage. This is due to the electrocapillary action that occurs between the gas pressure accumulated in the battery, the negative level of the electrode, and the surface tension at the electrolyte interface, and the electrochemical reaction in which oxygen gas in the air is reduced to O. It is thought that the cause is something.

の間からの漏液が短時間に大量に発生する。From this, 'g' in alkaline batteries! Leakage of electrolyte The leakage rate is high from the cathode sealing plate on the cathode side, but at this time, the leakage of the electrolyte itself is relatively small, and is more likely to occur between the positive 4ffi 1111 can and gasket. A large amount of liquid leaks in a short period of time.
このためかかる陽極側の漏液を左右する陰極金属缶での
封口構造が極めて庶要である。For this reason, it is extremely important to have a sealing structure for the cathode metal can, which controls leakage on the anode side.

A protruding seat 1a is formed near the inner opening,
A current collector rod 6 from which the cathode material 3 is led out to this protruding seat 1a

。- A metal support 7 is inserted into the step between the inner cylindrical part 51 and the outer cylindrical part 52 of this gasket 5, and the cathode sealing plate 8 is placed on this support 7, and in this state, the metal can There is one in which the opening of the can 1 is bent inward and tightened through the folded part of the gasket 5 to bring the inner wall of the can 1 and the gasket 5 into close contact to seal the can.

It is believed that it can be obtained.

In some cases, sufficient tightness could not be applied to the gasket 5 between the bent portion of the opening and the metal support 7, and this portion was not sufficiently effective in terms of leakage resistance.

耐漏液性を得られることになる。The relationship between the metal support 17 and the insulating gasket 15 at the time of sealing is explained in detail with reference to FIG. 3. First, when the opening of the metal can 1 is reduced in diameter to a predetermined size, the metal support 17 A pressing force is applied to the tapered portion 17a from the lateral direction, that is, from the radial direction, and the support 1
7 is a tapered portion 17a that extends upward in the figure, that is, the metal can 11.
A pushing force (■) acts in the direction of the opening. Therefore, in this state, the gasket 15 is bent by bending the opening of the metal can 11.
When a pressing force (■) is applied through the folding protrusion 155 of The tightening force at the wall 155 is significantly increased and good leakage resistance can be obtained in this area.

LR with 7a, type 6 alkali manganese' is pond [A]
50 batteries each with a different angle of the taper part 17a and 50 batteries of the same type as the conventional battery CB) were assembled at a temperature of 6.
After being stored for 45 and 90 days in an atmosphere of 0° C. and relative humidity of 90 tons, the number of leaking samples was examined, and the results shown in the table below were obtained. To measure the concentrated liquid here, place 1 on the top surface of the cathode sealing plate.
The resulting Alka'JK solution was visually inspected under 20x magnification, and a color reaction using a phenol red reagent was used.

液性が向上することが判明した。Table 1 below: Margin 1 However, in Table 1, if the angle of the tapered part is less than 30', the support itself will not have the strength to withstand the tightening force of the gasket, and if it exceeds 50', it will be susceptible to pressure from the lateral direction. Although the leakage resistance may be slightly reduced due to the inability to obtain sufficient upward pushing force, in any case, the battery obtained by this invention has better leakage resistance than conventional ones. It was found that sexual performance improved.
