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.
As a non-contact battery welding process, laser welding has corresponding advantages for lithium battery welding.
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.
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.
As external conductor a CuZn37 sheet of 0.2 mm thickness was welded at the negative pole of the cell. The negative tab of the battery cells is made of nickel-plated steel. Welding results for the 26650 lithium-ion cells and the chosen geometries of the weld areas are shown in Fig. 16.
