Since the lithium-ion battery system is composed of many unit cells, modules, etc., it involves a lot of battery welding technology. Common battery welding technologys are: ultrasonic welding, resistance spot welding, laser welding, pulse TIG welding.
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.
Brass (CuZn37) test samples are used for the quantitative comparison of the welding techniques, as this metal can be processed by all three welding techniques. At the end of the presented work, the suitability of resistance spot, ultrasonic and laser beam welding for connecting battery cells is evaluated.
As a non-contact battery welding process, laser welding has corresponding advantages for lithium battery welding.
Limiting the application of ultrasonic welding in lithium-ion electronic systems is mainly due to the low welding thickness (<3mm) of this battery welding method and the inability to achieve welding of high-strength material workpieces.
Most metals can be ultrasonically welded and the method is excellent for welding together thin foils, as well as thicker sheets (<3mm) which is very promising in battery applications (Tab welding, Busbar, nickel strip welding). Watch here a video of Ultrasonic welding of pouch cell Advantages:
