Description of the invention α)-[Background of the invention] The present invention relates to a sealed battery and a method for manufacturing the same; that is, the present invention relates to a sealed battery capable of inspecting electrolyte leakage, and more particularly Lithium-ion battery with high sensitivity and reliable inspection. -In sealed batteries such as lithium-ion batteries, after storing the battery elements in the battery can, the tops with external connection terminals, safety valves, and electrolyte injection ports are soldered, except for electrolyte injection. The sealed electrolyte injection port outside the mouth is filled with the electrolyte, and then, a sealing sheet is installed at the electrolyte injection port, and sealing processing is performed by laser welding, so as to manufacture a sealed battery. . When manufacturing a sealed battery, due to poor welding at the time of sealing or poor locking of the external connection terminal portion installed through the insulating member, leakage of the electrolyte or moisture in the external air may enter the battery. This phenomenon occurs. In a sealed battery with a bad seal, problems such as deterioration of battery performance and damage to the machine due to electrolyte leakage may occur. Therefore, in order to avoid shipment of defectively sealed batteries, leak inspection is performed. However, generally, the sealed battery after charging is inspected visually, and the surface of the battery is checked for leakage by the leakage of the electrolyte. ® and other visual inspections. However, in the inspection method performed by human vision, unevenness may occur due to the personal differences of the inspectors. At the same time, the leakage of the electrolyte may be caused in the state of the finely sealed defective parts and the like. , W

Description of the Invention (6) ^ Valve 16 and open electrolyte injection valve 12. As for the electrolytic solution, since the pressure reduction is performed on the basis of three radicals, the electrolytic solution is started to be injected into the battery can due to the difference in force between the battery can and the electrolytic solution. When starting to inject the electrolyte in the electrolyte port u, it is as shown in the following figure)-2 No, open the pressure valve that is combined with the electrolyte supply mechanism 7, ^ helium gas in the electrolytic material η The electrolyte should be relocated because 1 or 2? The electrolyte is injected into the battery can. At the same time, the helium gas is also injected into the solution. At the same time, the electrolyte injection port is filled and injected into the electrolyte. This causes the gas atmosphere to fill the battery. internal. In addition, when the electrolyte and helium gas are injected, the battery can is pressurized from the inside. Therefore, depending on the size and type of the battery can, the wall surface of the battery can expands and deforms. Occurs, and as a result, it is preferable to suppress deformation due to expansion of the battery can when pressurized. FIG. 3 is a diagram for explaining a mechanism for preventing deformation of a battery can. After the electrolyte is injected from the nozzle 7 for electricity and liquid injection, the pressure valve 18 is opened, and the electrolyte in the electrolyte port is pressurized by helium. The pressing mechanism 20 presses the wall surface 21 of the battery can 1 from both sides to prevent the wall surface 21 of the battery can} from being deformed. The pressure on the wall of the battery can is to match the pressure of the electrolyte in the can, and it is best to use a battery for extrusion. Take the same pressure as the housing force, the electrolyte and helium injection device of the present invention can be arbitrarily set according to the type of battery active material and the battery; within one pay \\ 312 \ 2d-code \ 90- 01 \ B9122232.ptd Page 10 565963 V. Description of the invention (7) The exhaust of part (7) is maintained for 2 seconds under the condition of exhausting from 1.07kPa to 1.33kPa for 5 to 7 seconds. After the pressure is reduced to about 10 minutes, and the vacuum is stable, and after confirming that there are no leaks, etc., the exhaust valve is closed and the electrolyte is injected, and 4 to 10 seconds after the electrolyte is injected. Then, the pressure valve is opened to facilitate pressurization with helium. 08MPa 至 0. 20MPa。 The pressure of helium, preferably the standard pressure of 0. 08MPa to 0. 20MPa. For example, if the liquid injection device of the electrolytic solution of the present invention is used, even if it is a viscous non-aqueous electrolytic solution, it can be installed in a battery with a length of 48 mm, a width of 30 mm, and a thickness of 6 mm in 60 seconds. Inject the electrolyte at the electrolyte injection port with a diameter of 1 mm. In addition, helium can be mixed with other rare gases, or nitrogen and carbon dioxide. However, when the content of gases other than rare gases is increased, the leak detection capability will be reduced. The content of rare gas such as helium is better, and even in rare gas, helium with a small molecule is preferred, and it is easy to pass through the fine leak. In this state, a method of injecting helium gas into the electrolyte from the liquid injection port 'can be performed by the following method; and,

It is explained that helium is introduced at the same time by using helium as the electrolyte solution injection. However, the injection can also be carried out separately: the completed battery can is filled with the electrolyte. Confined room

As shown by Wai Yuan (C), you can read the Ashikari for leak detection. 3 Within 2, perform 2 to facilitate the increase of the air pressure difference between the inside and outside of the battery of the test object, and a treatment like Heshu will increase the leakage rate from the fine leak-free parts and promote its leakage inspection. FIG. 5 is a diagram for explaining another example of the leak inspection method. A plurality of sealed batteries 31 can be accommodated and installed in the battery disc 35 in the leak detection chamber 32, and a helium leak detector provided in the leak detection chamber 32 can also be provided. 3 3. The helium concentration is measured by attracting the gas in the leak detection chamber 3 ^, and the state of helium is detected, which is the same as the state shown in FIG. 4 above. Inside 2, set up each of the detected battery disks and hermetically closed batteries 89122232.ptd Page 12 565963 V. Description of the invention (9) The cell, by means of helium; ^ Leak detector 3 3, attracts the drain The gas in the detection chamber 32 is measured, and the helium concentration is measured to identify the leaked battery. FIG. 6 is a diagram for explaining another example of the leak inspection method. This leak check method is to check the leak head sensor 3 6 of the helium gas leak detector 3 3 on the leaky parts around the sealed battery 31 where welding may occur, and confirm whether a leak occurs. The method can be confirmed by the method as described above. FIG. 7 is a diagram for explaining other examples of the leak inspection method, that is, a perspective view for explaining other examples of the leak inspection method. In a plurality of detection grooves 38 provided in the detection disc member 37, the sealed battery 31 for leak detection is received. The leak detection probe 39 can be installed in the test tank individually and hermetically. The top 40 can be used to measure the helium concentration in each test tank to facilitate the detection of leaks. Alternatively, after the detection top is installed, the measurement can be performed by depressurizing the inside of the detection tank. The detection top can also be installed by a transport mechanism that can move freely to any of the three axes of X, Y, and Z. At the same time, it can also be used to remove the battery that detects the leak. Mechanism to facilitate the automatic detection of leaks. In addition, the sealed battery containing helium of the present invention can also be applied to non-aqueous electrolyte batteries such as lithium ion batteries, batteries using polymer electrolytes, nickel-metal hydride batteries, and sealed lead batteries, and other aqueous electrolyte batteries. on. The helium-containing sealed battery of the present invention can be used for transmission measurement.
