Abstract: The electromagnetic pulse welding (EMPW) technology has been paid much attention in connecting lithium-ion battery (LIB) laminated tabs due to its advantages of high efficiency and no powder lose. Compared to double-layer workpieces, the EMPW of laminated workpieces involves a more complex electromagnetic force distribution and motion characteristics, and the interaction mechanism is not yet clear. Therefore, based on a method of collision point offset combined with interlayer air segmentation, an electric-magnetic-mechanic multi-physics field coupling simulation model of laminated tabs EMPW process was built. A comprehensive experimental platform was established to carry out EMPW experiments. The electromagnetic force distribution and the motion characteristic of tabs were analyzed layer by layer. The results showed that the electromagnetic force was the largest in the tab closest to the coil, and the shielding effect reduced electromagnetic forces in other tabs. In the motion of tabs, collisions and rebounds occurred many times, and welding could only be achieved when tabs collided with each other. Moreover, tabs closer to the battery cover plate were easier to be welded. The discharge voltages did not change the motion characteristic of tabs but affect the welding effect. This study can provide a scientific basis and experimental foundation for the effect regulation and engineering applications of the EMPW LIB laminated tabs.
