6 FAQs about [Lithium battery rack welding]

Why is laser welding used in lithium ion batteries?

Laser welding is widely used in lithium-ion batteries and manufacturing companies due to its high energy density and capability to join different materials. Welding quality plays a vital role in the durability and effectiveness of welding structures. Therefore, it is essential to monitor welding defects to ensure welds quality.

Which welding techniques can be used for connecting battery cells?

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.

Can a battery cell casing be welded?

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.

How are battery cells welded?

Different welding processes are used depending on the design and requirements of each battery pack or module. Joints are also made to join the internal anode and cathode foils of battery cells, with ultrasonic welding (UW) being the preferred method for pouch cells.

Does ultrasonic welding cause damage to lithium ion cells?

The highest heat input occurred at ultrasonic welding, but for all welding techniques the heat was very localized and no damaging temperatures occurred at the lithium-ion cells. The results presented in this paper were gathered within the research project EEBatt, funded by the Bavarian Ministry of Economic Affairs and Media, Energy and Technology.
