Analysis of the advantages of laser welding of lithium batteries

The advantages of power lithium-sulfur battery laser welding are that the loss of welding material is small, the deformation of the welded workpiece is small, the performance of the equipment is stable and easy to operate, the welding quality and the degree of automation are high. The advantages of its process are the characteristics that other welding methods cannot compare as follows: ●Energy accumulation, high welding efficiency, high production accuracy, and large weld depth-to-width ratio. The laser beam is easy to focus, align and be guided by optical instruments. It can be placed at an appropriate distance from the workpiece, and can be guided between fixtures or obstacles around the workpiece. Other welding methods cannot be used due to the above-mentioned space limitations. ●The heat input is small, the heat affected zone is small, the residual stress and deformation of the workpiece are small; the welding energy can be accurately controlled, the welding effect is stable, and the welding appearance is good; ●The lithium battery laser welding can be accurately controlled, the focus spot is small, and the high-precision positioning, It is easy to realize automation with mechanical arm, improve welding efficiency and reduce cost; ●Non-contact welding, optical fiber transmission, good accessibility and high degree of automation. When welding thin materials or thin-diameter wires, it is not as easy to be troubled by reflow as arc welding. The high-efficiency and precise power lithium battery laser welding machine can greatly improve the safety and service life of automobile power lithium-ion batteries, and will bring revolutionary progress in future automobile power technology; there are many laser welding parts for power lithium batteries, which have pressure resistance and For leak detection requirements, most of the material is aluminum, because the welding is difficult and the welding process is more demanding.
