This paper reviews tab-to-busbar interconnections in lithium-ion battery packs, focusing on resistance welding (RW), laser beam welding (LBW), and ultrasonic welding (USW). The functional roles of tabs and busbars and typical material choices (Al-, Cu-, and. In recent years, Laser Welding Aluminum Conductors has emerged as a precise method for joining aluminum in high-voltage cables, automotive wiring harnesses, and power transmission lines. Aluminum conductors offer a unique combination of low cost, high electrical conductivity, and light weight. Weld your busbars with ultrasonics to permanently benefit from strong connections without contact resistance — even with different metals like aluminum and copper. Discover the benefits of our innovative welding technology for more output, control, and efficiency in your production! to 12 s per. Aluminum (Al) and copper (Cu) are among the common materials for busbar and battery tab manufacturing. A wide range of research shows that the laser welding of busbar to battery tabs is a very promising technique. Subsequently. Busbars are an important component of battery design.
