Since the lithium-ion battery system is composed of many unit cells, modules, etc., it involves a lot of battery welding technology. Common battery welding technologys are: ultrasonic welding, resistance spot welding, laser welding, pulse TIG welding.
Selecting the correct nickel strips is crucial for successful spot welding of lithium batteries. Here’s some advice: Thickness: Choose nickel strips that are the appropriate thickness for the battery cells. Thicker strips provide more strength but may require higher welding power.
Tabs and Busbars: These are tiny metal strips that join the different battery cells in a pack together. Usually, nickel or nickel-plated steel is used to make them because of its excellent conductivity and weldability. How is spot welding performed on lithium-ion batteries?
As a non-contact battery welding process, laser welding has corresponding advantages for lithium battery welding.
Lithium-ion batteries contain flammable electrolytes, making safety a paramount concern during spot welding. Some key safety measures include: Proper ventilation: For the purpose of eliminating heat and fumes produced during welding, adequate ventilation is required.
Brass (CuZn37) test samples are used for the quantitative comparison of the welding techniques, as this metal can be processed by all three welding techniques. At the end of the presented work, the suitability of resistance spot, ultrasonic and laser beam welding for connecting battery cells is evaluated.
