The advantages of power lithium-sulfur battery laser welding are that the welding material loss is small, the deformation of the welded workpiece is small, the equipment performance is stable and easy to operate, and the welding quality and automation are high. Its technological advantages are incomparable with other welding methods as follows:

The energy is concentrated, the welding efficiency is high, the machining accuracy is high, and the welding seam aspect ratio is large. The laser beam is easy to focus, align, and guided by optical instruments. It can be placed at an appropriate distance from the workpiece, and can be redirected between fixtures or obstacles around the workpiece. Other welding laws cannot be used due to the above-mentioned space constraints.

Small heat input, small heat affected zone, small residual stress and deformation of workpiece; precise control of welding energy, stable welding effect and good welding appearance;

Lithium battery laser welding can be precisely controlled, with small focusing spot and high-precision positioning. It is easy to realize automation with robotic arms, improve welding efficiency and reduce costs;

Non-contact welding, optical fiber transmission, good accessibility and high degree of automation. When welding thin or thin wire rods, there is no problem of melting back like arc welding.

High-efficiency and precise power lithium battery laser welding machine can greatly improve the safety and service life of automotive power batteries, and will bring revolutionary progress to future automotive power technology; power lithium batteries have many laser welding parts, with withstand voltage and night leakage tests. Requirements, most of the materials are aluminum, because the welding is difficult, and the requirements for the welding process are higher.

As the core component of new energy vehicles, the quality of power lithium battery welding basically determines the safety and quality of the entire new energy vehicle. It is these laser advantages that make laser welding machines successfully applied in power battery welding processing. And with the further improvement of new energy vehicle technology, it will promote the further optimization and upgrading of power lithium battery welding machine technology to a certain extent.
