In summary, welding the thicker, more conductive tabs used in today's more efficient, higher capacity battery packs can be challenging, but welding success can be achieved by designing the parts correctly and selecting equipment that is best suited to the application.
To meet this growing demand, SIL has developed the Lithium Ion Battery Laser Welding Machine. This innovative machine enables precise welding of prismatic cells made from materials such as aluminum, aluminum alloy, stainless steel, or OFHC Copper. It is capable of welding components with a thickness ranging from 0.5 mm to 3 mm.
Whether to power our latest portable electronic device, power tool, or hybrid/electric vehicle, the removable battery pack is essential to our everyday lives. Tab-to-terminal connection is one of the key battery pack welding applications.
The bottom line: with the correct fiber laser welding equipment and process, laser welding is proven to consistently produce high quality welds in 3000 series aluminum alloys that have connections within dissimilar metal joints. The production of Li-ion batteries requires multiple welding processes.
