With the continuous development of technology, lithium batteries have become an indispensable part of modern society. In the production process of lithium batteries, laser welding technology is also increasingly widely used.
Principle Of Laser Welding Process For Lithium Battery
Laser welding of lithium battery is a method of welding lithium battery with high-energy density laser beam. In the process of laser welding, the lithium battery needs to be placed at a fixed position first, and then the laser beam is irradiated to the weld of the lithium battery by controlling the direction and energy of the laser beam. Due to the large amount of metal elements contained in lithium batteries, these metal elements will melt and vaporize under laser irradiation, forming a high-temperature and high-pressure environment. When this environment reaches a certain level, the two welding seams in the lithium battery will fuse together to form a complete welding structure.
Characteristics Of Laser Welding Process For Lithium Battery
- Efficiency: Compared with traditional welding methods, lithium battery laser welding has higher efficiency. This is because laser welding can complete a large amount of work in a short time, and does not need to use any auxiliary materials.
- High precision: lithium battery laser welding can achieve very high precision. Because the laser beam can be accurately focused on the weld seam, ensuring the quality and stability of the welding.
- Environmental protection: laser welding of lithium battery will not produce any harmful substances, so it is very friendly to the environment. In addition, since no solvents or other chemicals are required, the generation of waste can also be reduced.
- Wide scope of application: lithium battery laser welding can be applied to various types of lithium batteries, including lithium ion batteries, polymer lithium ion batteries, etc. In addition, it can also be applied to various materials, such as aluminum, copper, stainless steel, etc.
