5. Wide Applicability: Laser welding of lithium-ion batteries can be applied to various types of lithium-ion batteries, including lithium-ion, polymer lithium-ion, and NMC lithium-ion batteries. Additionally, it can also be applied to various materials, such as aluminum, copper, stainless steel, etc.
There are many parts that need to be connected in the battery system, and welding is often the most effective and reliable connection method. Laser welding has the advantages of non-contact, high energy density, accurate heat input control, and easy automation, which is considered to be the ideal choice for electric vehicle battery manufacturing.
The design and welding quality of the automatic laser welding machine will affects the cost, quality and safety of lithium battery packs. DPLASER, many years of experience in industrial laser equipment production, has developed an automatic laser welding machine designed for battery module manufacturing.
Macroscopic and microscopic examination of welds ASTM E 604-83, Standard test method for dynamic tear testing of metallic materials. Hardness test method of laser weld metal (ISO 22826. Currently a pre ISO draft). In spite of all the above, there is still a shortage of standards specific to laser welds in metallic materials.
Since power batteries need to have multiple welding parts and it is difficult to carry out high-precision requirements met by traditional welding methods, laser welding technology can weld welds with high quality and automation due to the characteristics of small welding consumables loss, small deformation, strong stability and easy operation.
No.: DE-69572-01 With the support of Fraunhofer ILT, an additional laser welding process was developed to produce a safety component, which is additively welded to the battery cell within the overall system. Thus, the portfolio of laser welding tasks could be extended thanks to the high system fl exibility.
