Free QuoteTo meet the high joining demand and low cycle time, laser welding is emerging as the main joining technology due to its ability to weld a variety of materials at a high speed. This paper investigates laser overlap welding for producing similar and dissimilar material tab-to-busbar interconnects for Li-ion battery assembly.
Cooper is traditionally used as busbar material. But the selection of Al busbar material over Cu busbar can reduce the weight and cost of the busbar used in the battery module by 75%. However, the Cu tab to Al busbar gave slightly higher (about 16–20%) resistance over the Cu tab to Cu busbar joint.
To investigate the application of laser welding in the production of lithium battery modules for electric vehicles, this study employs the finite element method to simulate the welding process of lugs and busbars in lithium batteries under different parameters.
The choice of tab and busbar materials to produce those electrical interconnects is mainly based on weldability, weight, electrical/ thermal conductivity and cost. To meet the high joining demand and low cycle time, laser welding is emerging as the main joining technology due to its ability to weld a variety of materials at a high speed.
For all battery cell technologies, whether cylindrical, prismatic, or pouch, conductive busbars are used to connect individual cells into modules.
The Fastest Module Busbar Welding Laser welding is capable of making more busbar-to-terminal welds per second than any other metal joining process, enabling manufacturers to dramatically increase module throughput. Ultra-Consistent Welding Results
