Since the 1990s, ultrasonic metal welding has been widely used by battery and EV makers because it is able to bond very thin materials — down to 5 µm foils — and can do so in assemblies of 100 layers or more. This capability is essential to successful assembly of high-power lithium batteries and super capacitors. At the same time, the
Ultrasonic metal welding process characteristics. Although ultrasonic metal welding is well-suited for battery welding in volume production.

Critical to the assembly of all these battery designs is a metal-joining technology — ultrasonic metal welding. Since the 1990s, ultrasonic metal welding has been widely used by battery and EV makers because it is able to bond very thin materials — down to 5 µm foils — and can do so in assemblies of 100 layers or more.
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 .
Recently, some research has been carried out on the ultrasonic welding of multi-stacked batteries. Kang et al. [2012; 2013] presented the effect of structural multilayer battery tab configuration. Lee et al. conducted research on the coupled finite element model. In their study, the temperature distribution within the
When multiple batteries are joined into larger battery modules and modules are joined into a pack, the ultrasonic process handles welds involving busbars, harnesses and cables. For these larger welds, a lower frequency of 20 kHz with a higher amplitude is often used.
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.
