Application In The Production Of Aluminum Shell Batteries

Ultrasonic welding of copper, aluminum and other non-ferrous metals is a mature joining process, widely used in automotive, consumer electronics and other fields. Due to the rapid development of new energy electric vehicles, the demand for lithium-ion batteries is also increasing, and the application of ultrasonic welding of copper and aluminum foils has also increased significantly.

Reliable Connection Of High-Voltage Cables For Electric Vehicles

The electric motor used in electric vehicles must be able to provide full power output at startup. This requires a reliable connection of the high-voltage cables in the vehicle. The cables and plugs between the charging post and the high-voltage battery require a reliable connection with low contact resistance for fast charging. Design engineers require solder widths that are as narrow as possible to save installation space. However, this is difficult to achieve with conventional techniques, and reliable connections can now be easily achieved using ultrasonic welding.

Ultrasonic Welding Of Flexible Pack Batteries And Power Semiconductors

The welding of copper and aluminum foils for flexible pack batteries is also a typical ultrasonic welding application. Another ultrasonic welding process is used for the production of IGBT power semiconductors. IGBTs are key electronic components that switch current quickly and with little loss and are used as power converters in electric drives and battery charging systems. Ultrasound is particularly suitable for IGBT welding on sensitive ceramic substrates.
