Laser welding process for aluminum shell of power Ni-MH battery pack
Electric vehicles have been favored since their advent because they reduce emissions and achieve zero emissions. Electric vehicles rely on power lithium-ion batteries for power supply, and power lithium-ion batteries are usually made of 3003 aluminum alloy. Aluminum batteries must be welded together to protect the internal electrode material and prevent electrolyte leakage. However, traditional welding packaging methods can no longer meet the needs of the rapid development of power batteries, and laser welding technology has good adaptability to aluminum shells of power batteries. How to use the laser welding process for aluminum shells of power lithium-ion batteries?
Laser welding can be divided into side welding and top welding. The important advantage of side welding is that it has little impact on the inside of the battery, and spatter is not easy to enter the inside of the battery shell.
Since bulges may appear during welding, which has a slight impact on the assembly of subsequent processes, the side welding process has high requirements for the stability of the laser and the cleanliness of the material. However, since the top welding process is welded on one surface, the requirements for the integration of welding equipment are low and mass production is simple. However, there are also two disadvantages. One is that there may be a little spatter during the welding process of the battery, and the other is that the production requirements of the front of the aluminum shell of the power Ni-MH battery pack are high, which will lead to cost problems.
The most important process in the square battery welding process is the encapsulation of the shell, which can be divided into the welding of the upper cover and the lower cover according to different positions. Some power Ni-MH battery pack manufacturers use deep technology to process the aluminum shell of power lithium-ion batteries because the processed battery volume is not large, so only the top welding is required.
Electric cells used for power lithium-ion batteries follow the principle of portability. In addition to the use of light aluminum materials, they must be thinner. The general shell, cover, and base are basically required to reach 1.0 mm. The thickness of the basic materials of mainstream manufacturers is about 0.8 mm.
That's it for the laser welding of battery aluminum shells. The wall thickness of the aluminum shell used for power Ni-MH battery pack encapsulation is 0.8mm. The quality of the laser beam used for laser welding is very good, with high power stability and high power. The aluminum shell used for welding power lithium-ion batteries has a very good effect. When processing the aluminum shell of power lithium-ion batteries, in addition to mastering its welding process, surface oxidation treatment is also very important. We have talked about the surface oxidation treatment of the aluminum shell of power lithium-ion batteries, and you can learn about it together.
