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.
The findings are applicable to all kinds of battery cell casings. Additionally, the three welding techniques are compared quantitatively in terms of ultimate tensile strength, heat input into a battery cell caused by the welding process, and electrical contact resistance.
Furthermore, battery tabs or connector bars with a thickness of several millimeters can be joined by keyhole welding , . Especially for metal surfaces, the reflection of the laser beam is problematic, because it can damage objects in close vicinity.
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.
The counterpart has to be fixed but may have any thickness. It was reported that ultrasonic weld vibrations can damage the inside of a pouch cell, especially when the conductors inside the battery cell are also ultrasonically welded. In order to prevent the propagation of the vibrations into the cell, the terminal tabs need to be clamped .
The highest temperatures occurring in a hot spot at the external conductor will not harm a battery cell but the temperatures inside the casing, which arise at the electrochemically active materials, are of special interest. In lithium-ion cells, the electrochemically active materials are in direct contact with the cell casing .
