The circuit board of this spot welder can be used for welding 18650/26650/32650 lithium batteries. A battery with a large discharge current will directly affect the welding effect. Features: High
In energy storage systems, lithium batteries stand out. Solid terminal connectors ensure that power is stored effectively. For a solid grip, the terminal contains a hole for screw securing. The dimensions, typically 8mm to
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 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 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.
The reliable production of high-quality lithium-ion battery components still poses a challenge, which must be met to cope with their rising demand. One key step in the production sequence is the process of cell-internal contacting, during which the electrode carrier foils of the anode and the cathode are joined with the arrester.
CuZn37 sheets welded on negative terminal of 26650 lithium-ion cells; from left to right: resistance spot weld, ultrasonic weld, laser beam weld. These welding processes were recorded by the thermographic camera A325sc by Flir.
Conclusions and Outlook Through an experimental study, it was shown that μFSSW is a promising new joining technology for internal contacting in prismatic lithium-ion battery cells. Spot welds were fabricated for stacks consisting of 30 aluminium and 30 copper foils with two different tools (with and without a probe).
