For current storage systems for hybrid and fully electric vehicles (HEVs / FEVs), the lithium-ion battery is currently the favorite. Ultrasonic welding is relied on both for contacting the anodes and cathodes as well as for linking the cells to each other.

The demands placed on the joining method are very high in this application. On the one hand, different combinations of materials are used; on the other hand, it is imperative that no significant increase in temperature take place during the process, due to the highly-sensitive cellular chemistry.

As a friction-welding process with little heat input, ultrasonic metal welding is optimally suited for such cases.

Comprehensive process control and good potential for automation are further demands that are satisfied by this method.
