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.
This welding process is used primarily for welding two or more metal sheets, in case of battery it is generally a nickel strip and positive terminal/negative terminal of the battery together by applying pressure and heat from an electric current to the weld area. Advantages: Low initial costs.
It features 5kHz fast feedback, and operates in constant current, voltage or power feedback modes. Voltage feedback is the typical mode of choice when welding battery packs, but the IPB-5000A can also weld in “combo mode” (current and voltage) to address even the most challenging battery welding applications.
Safety is another concern when selecting resistance welding equipment for battery welding. For example, if not welded properly, the chemicals contained in lithium ion batteries (you’ve heard about this in the news recently, associated with the new Boeing 787 aircraft) can leak out, burning eyes and skin.
Most metals can be ultrasonically welded and the method is excellent for welding together thin foils, as well as thicker sheets (<3mm) which is very promising in battery applications (Tab welding, Busbar, nickel strip welding). Watch here a video of Ultrasonic welding of pouch cell Advantages:
Can be used to weld critical parts like battery tabs and foils. Challenges faced by using laser welding: Wire bonding is well matured technology which was invented for the semiconductor industry and standard technology for semiconductor chips since 1970s, and also Tesla and ola electric batteries are wire bonded.
