Battery extrusion has increasingly become a preferred method in battery pack assembly, especially when compared to traditional laser welding techniques. This shift is attributed to several key factors that enhance manufacturing quality and efficiency. First, battery extrusion offers superior mechanical strength and durability. Unlike laser welding, which can sometimes create weak spots due to heat-affected zones, extrusion forms a continuous bond that ensures stronger structural integrity of the battery cells. This leads to a more reliable and longer-lasting battery pack. Second, battery extrusion reduces the risks associated with heat damage. Laser welding involves intense localized heat, which can compromise sensitive battery components, potentially leading to safety hazards such as thermal runaway. Extrusion, by applying pressure without high heat, preserves the integrity of lithium layers and internal electrodes. Furthermore, extrusion enables faster production speeds and scalability for lithium electric stacking machines. This efficiency gain translates into higher output and cost savings, meeting industrial demands for rapid battery pack assembly. Finally, the use of battery extrusion aligns well with modern pack equipment designed for precision and automation. It integrates seamlessly with stacking machines, ensuring consistent quality and reducing manual labor dependency. In conclusion, battery extrusion represents a notable advancement over laser welding in the realm of lithium battery manufacturing, offering improved safety, strength, and efficiency in pack equipment applications.
