New energy battery manufacturing and energy storage systems require high-precision, low-resistance structural joints to ensure optimal electrical conductivity and thermal safety. Yizen develops specialized fiber laser welding systems engineered for electric vehicle (EV) battery module assembly and automated PACK production line integration.
Battery fabrication frequently involves highly reflective metals—such as copper and aluminum—and demands stringent penetration control to prevent thermal damage to internal cell components or separators. Fiber laser welding delivers concentrated energy density and narrow weld profiles, ensuring stable, crack-free joints for busbar connections, cell-to-busbar tabs, and battery enclosure sealing.
System configurations are customized based on specific cell geometries (prismatic, cylindrical, or pouch), required toolpaths, and automated line throughput constraints. Our engineering team provides comprehensive technical evaluations, equipment layouts, and process validations directly from your product specifications and project timelines.
