Description of the invention (/) Background of the invention The invention relates to a battery container made of a protective metal plate, which is used as a battery container for various types of batteries. Especially lithium-ion batteries for mobile phone power. Traditionally, aluminum has been used as a battery container material because of the highly corrosive non-aqueous solution contained in the aforementioned lithium ion battery and its excellent formability. However, the strength of aluminum battery containers is lower than that of steel plates. For example, when a metal cap is mounted on one end of a container, the solution solution may leak out due to insufficient calking force. On the other hand, if the thickness of the container is increased in order to ensure the strength, the space for the solution and the like in the battery will become smaller, and the battery will be heavier. The present invention is to solve these problems, and an object thereof is to provide a battery container ′ which has a large capacity, good corrosion resistance, good sealability, and prevents solution leakage due to improvement in mechanical strength. In order to accomplish the above object, a battery container made of a metal sheet with a surface protection as described in item 1 of the patent application scope is characterized by deep drawing (DI and drawing and ironing). ) Is made of a protective metal plate, which is a nickel-coated steel plate covered with aluminum, in the shape of a cylinder with a bottom, and the aluminum plate is on its inner surface. The aluminum plate is used as a component on the inner surface of a battery container. The solution to be packaged in the container has excellent corrosion resistance. However, in view of the insufficient mechanical strength of the aluminum plate, the aluminum nickel-coated steel plate is used as the outer surface _ 3 This paper size applies to the Chinese National Standard (CNS) A4 Specifications (2 丨 0X297mm)!, ^, Clothing _ order line.

Invention Explanation (>) The module is because it can strengthen the strength of the battery container, and can easily and reliably attach a lid, etc. to the battery container, while at the same time surely preventing the solution from leaking to the outside. A battery container made of a protective metal plate. It is characterized in that the protective metal plate is made of the aforementioned nickel-plated steel plate and a name plate that are alternately overlapped and then pressurized by cold wave pressure, and before that, the aforementioned nickel plating The bonding interface between the steel plate and the aluminum plate is pre-treated in a vacuum chamber in advance. The pre-activation processing is performed under an inert gas environment of ultra-low pressure from 1 X 1CT1 to 1 X 10.4 · Torr, and the above-mentioned bonding interface has Nickel-plated steel plate and aluminum plate respectively serve as the ground metal electrode A and the counter electrode B insulated from the ground. Between them, RF power in the frequency range of 1 to 50 MHz is applied to introduce a glow discharge to perform a sputter etching process and be exposed to the foregoing. The area of the electrode of the glow discharge plasma is less than 1/3 of the electrode B. For example, the battery container made of a metal sheet with a protective surface in item 3 of the patent application is characterized in that the thickness of the metal sheet with the protective surface is 0.2 to 0.5 mm, And the thickness of the aluminum plate is 20 to 70% of the thickness of the cladding metal plate. The reason for the thickness of the cladding metal plate is 0.2 to 0.5 mm as follows: From the viewpoint of ensuring corrosion resistance, since the aluminum plate must reach a certain thickness or more Therefore, the thickness of less than 0.2 mm cannot provide sufficient thickness of the nickel-plated steel sheet, and therefore does not have sufficient strengthening effect. On the other hand, if the thickness exceeds 0.5 mm, it may cause insufficient internal capacity of the battery container. In addition, the thickness of the aluminum plate It is 20 to 70% of the thickness of the metal sheet. The reason is that if the thickness is less than 20%, there is insufficient corrosion resistance. However, if it exceeds 70%, the thickness of the nickel-plated steel sheet cannot be sufficient, resulting in __4_.

Description of the invention (f) Detailed description of the preferred embodiment The present invention will be explained more specifically with reference to the accompanying drawings. First, examples of the battery container composition of the present invention will be described. Figure 1 shows that the battery container 10, including the bottom container, is formed by deep drawing or DI. Secondly, the finished battery can be obtained by filling the battery container 10 containing the solution and other battery components through the top opening through the lid. As shown in FIG. 1, the battery container 10 is made of a deep-drawn or DI-formed protective metal plate, and has a double-layered composition having a substantially uniform thickness throughout. That is, the battery container 10 has an aluminum plate 11 as an inner surface component, and a nickel-plated steel plate 12 as an outer surface component. The aluminum plate 11 and the nickel-plated steel plate 12 are closely adhered together as one body. To produce such a composition, sufficient corrosion resistance can be obtained by the aluminum plate 11 on the one hand, and mechanical strength can be ensured by the nickel-plated steel plate 12 on the other. In addition, the ore-nickel steel plate 12 can effectively prevent the appearance of the battery container from rusting because the nickel-plated layer 14 is applied to the outer surface of the steel plate 13. In addition to the cylindrical battery container often used, the present invention can also be applied to a square. In this case, a square punch or die should be used. Next, a method for manufacturing the battery container 10 made of the above-mentioned protective metal plate will be described. First, please refer to 2 to describe the manufacturing method of the sheet metal material of the battery container 10. The aluminum strip 22 and the nickel-plated steel strip 23 are unrolled from the reels 20 and 21 and bypass the electrode rollers 25 and 26. Each of them is exposed in the etching chamber 24, and the two strips are activated by sputtering etching. _______6_ The scale is applicable to the middle store ^^ (CNS > Λ4 specification (210X297) '' '--- Γ, ---!-; --- install ------ order ------ line (2 Please read the notes on the back before filling this page) Printed by the Consumer Standards Department of the Central Bureau of Standards, Ministry of Economic Affairs, printed A7 B7 ___ V. Description of the invention (0 ✓ As disclosed by the applicant of the present invention in Japanese Patent Application Laid-Open No. 1-224184 The pre-activation treatment is performed in an inert gas environment from IX 1〇_1 to 1X10-4 Torr. The aforementioned aluminum plate and nickel-plated steel plate with bonding interface are used as the ground metal electrode A and the counter electrode insulated from the ground, respectively. B, during which RF power in the frequency range of 1 to 50 MHz is applied to introduce a glow discharge 'for sputtering etching treatment', and the electrode surface exposed to the aforementioned glow discharge plasma is less than 1/3 of electrode B. After that, In the vacuum chamber 27, the two metals are cold-rolled by a rolling unit 28, and then the cover metal plate 29 is rolled up on the reel 30. After the cover metal plate 29 is cut to the required size, it is formed by DI. In other words, as shown in Fig. 3. In other words, the protective metal plate is firstly formed into a specific electric and battery container 10 by general deep drawing. The final product has a larger outer diameter and a shallow bottomed container 31. Thereafter, the coaxial shrinkage dies 32 to 35 are given to this bottomed container 31 two or more times, so as to sequentially reduce the diameter of the deep drawing shrinkage, and The punch 36 continuously passes the last shrinking die to obtain the battery container. The diameter of the deep-drawing is the outer diameter of the final product of the electric and battery containers. The continuous deep-drawing pressure can make the battery container smooth inside and outside. Although for the sake of explanation, in the example, multiple shrink molds are arranged in a coaxial manner, in fact, it is not particularly necessary to form a bottomed container in a coaxial manner. As described above, according to the scope of the patent application The battery container of item 1 is made of a protective metal plate by deep drawing or DI forming, and the protective metal plate is a nickel-plated steel plate covered with aluminum, and the shape is a cylinder with a bottom.
