Laser welding is widely used in lithium-ion batteries and manufacturing companies due to its high energy density and capability to join different materials. Welding quality plays a vital role in the durability and effectiveness of welding structures. Therefore, it is essential to monitor welding defects to ensure welds quality.
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.
Most manufacturing industries use ultrasonic welding in welding lithium-ion batteries. The ultrasonic spot welding method uses high-frequency ultrasonic vibrations to weld similar or dissimilar materials. Reliable standards for welding an advanced lithium ion batteries are one of the key components in manufacturing electric vehicles.
However, laser welding in battery packs is quite different from the laser welding inside battery cells. Laser welding outside the cells is usually of penetration welding while laser welding inside the cells is usually of seam welding.
Laser welding in lithium-ion prismatic cell were tested under different load modes. Fast development of finite element models of laser welding was proposed. Deformation and failure behaviors of prismatic cell with laser welding were properly predicted.
