Customer ServiceBrass (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.
Parameter control also allows LBW to adapt to the thickness of the material tabs and can create thin or thick weld nuggets. In battery cell welding it is important to create thin welds due to the relatively thin battery cases and the risk of the weld penetrating the case and thus damaging the core.
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.
Battery cells are most often put into modules or packs when produced for electrically driven vehicles. The variable of greatest influence when welding battery packs is the contact resistance between the cell and the connection tab. It is crucial to minimize this variable as much as possible to prevent energy loss in the form of heat generation.
The processability of welding nickel strip is provided by its rectangular section, thickness 0.127 -0.2 mm and width 5-10 mm. Such form factor provides stability of strip length, tight fit on a flat surface of the positive contact of small batteries with 18350 or 18650 typical size. This is convenient for further welding.
This therefore provides a highly controlled method of developing localised welding temperatures that are suitable for joining materials up to 0.5 mm thick onto conductive battery cans.
