Common battery welding technologys are: ultrasonic welding, resistance spot welding, laser welding, pulse TIG welding. This post combines the application results of the above battery welding technologies in lithium-ion battery systems, and explores the influencing factors. Ultrasonic welding is a solid state battery welding process.
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.
UWB is also suitable for creating electrical connections between cylindrical battery cells. Although proper fixation of the cell is paramount for the welding, as any significant lateral movement will reduce the vibration amplitude and consequently diminish the power of the welding process.
Since laser welding has the smallest heat-affected zone in all battery welding processes and can be applied to the connection of multi-layer sheets, laser welding is considered to be the most effective battery welding process for lithium batteries. There are many factors affecting the battery welding process of laser welding.
