おける強固な封口状態の確立が急務である。Structures of conventional examples and their problems Alkaline batteries that are generally constructed using alkaline electrolytes, such as silver oxide batteries, manganese dioxide batteries, nickel-zinc batteries, and lithium batteries that use organic electrolytes, are characterized by the characteristics of the electrolyte. If the sealing strength is weak, the built-in electrolyte will leak onto the battery terminal surface, causing corrosion of the terminal surface and damage to the equipment used.
It was extremely inconvenient. In order to solve these problems, it is urgently necessary to establish a strong sealing condition between the metal sealing plate, the metal case, and the sealing bunkering.

もその材料硬度(ピップ。Conventionally, the purpose is to increase the mechanical strength of the periphery of the metal sealing plate when sealing the metal case by bending the upper end of the opening inward and pressing the sealing punch against the periphery of the metal sealing plate. Then, the peripheral edge of the sealing plate is bent in a direction almost perpendicular to the radial direction of the sealing plate and has a U-shaped cross section, and this U-shaped bending part applies a U force, and the U-shaped bending is Leak resistance was ensured by firmly attaching a backing to the tip of the part to an appropriate size. However, the materials for the sealing plate and case of this type of battery are usually stainless steel, phosphor bronze, nickel silver, or nickel steel plate with a thickness of about 0.1 to 0.6 mm.
However, these materials vary somewhat depending on their thickness, or at least their material hardness (pips).

However, it is difficult to process a material with such hardness into an arbitrary shape, and in reality, materials with a hardness of about 100 to 150 are used. In this case, the sealing plate is slightly deformed due to the concentrated load during sealing. In other words, if the peripheral edge of the sealing plate is bent into a U-shaped cross section, the inner side wall of the sealing plate will shift inward as shown by the broken line in Figure 1, and as a result, the metal sealing plate, The sealing compressive strength between the sealing donkey, king, and case tends to decrease, making it difficult to achieve a satisfactory sealing condition.

折9返し部5aに強固に圧接させて気密封口を行なう。When fixing the trapezoidal deformation prevention body 7 to the sealing plate 5 configured as described above, the nail-shaped current collector 6 is inserted into the soft material 9 of the trapezoidal deformation prevention body 7, and then the current collector 6 is fixed. is passed through the hole 11 of the trapezoidal deformation prevention body 7, and the trapezoidal deformation prevention body 7
The entire peripheral edge of the sealing plate 5 is press-fitted and fixed to the inner side wall of the sealing plate 5. Synthetic rubber, synthetic resin, etc. having elasticity and electrical insulation properties are fitted onto the peripheral edge of the sealed current collector constructed in this way.
Alternatively, a sealing body is formed by integrating the material by molding, and the battery case 1 is inserted into the step 1a provided on the abdomen while the battery case 1 is opening, and then the opening end 1b of the battery case 1 is bent inward. The sealing panoking 12 is firmly pressed against the peripheral folded portion 5a of the sealing plate 5 to achieve an airtight seal.

封口気密性はさらに高捷る。By performing such sealing, the force of displacement of the inner surface side wall of the sealing plate in the inner radial direction due to the stress load on the sun is absorbed by the peripheral edge of the trapezoidal deformation prevention body 7 (thereby holding and fixing it). Deformation of the sealing plate 5 can be prevented, and as a result, an extremely good and stable sealing state can be achieved.The surface of the trapezoidal deformation prevention body 7 is lined with a highly flexible rubber or plastic material by a method such as lining. If provided, the airtightness of the seal will be even higher.

Conventional configuration, that is, trapezoidal deformation prevention body 7
The leakage resistance was compared with those A' and B' which did not have the soft material 9. In this case, manganese dioxide battery A uses a 10 molar potassium hydroxide aqueous solution as the electrolyte, and lithium battery B uses a solution of 1 mono I/// l of lithium borate dissolved in γ-butyrolactone. was used, and ribbon-shaped lithium was used as lithium. In addition, as the material for the sealing packing, nylon 11 was used in the case of manganese dioxide batteries, and low density polyethylene was used in the case of lithium batteries. Furthermore, a butyl rubber material was used as the soft phase 9.

The diffusion of mercury from zinc chloride to the current collector surface and the diffusion of alkaline electrolyte based on the diffusion are also ensured by the strong adhesion between the soft material provided in the trapezoidal deformation prevention body and the current collector. It is preventable.
