Typically, power battery is a new clean energy and currently a research hotspot across the world. It is a kind of storage battery providing the power source for such vehicles as an electric car, electric train, electric bicycle and golf cart. It has been applied to a wide range of industries and become part of people’s lives. (Power battery Manufacturer China)

Power battery is mainly made up of anode material, cathode material (carbon material), separator, electrolyte, battery shell, etc. As the core component of new energy vehicles, it directly determines the vehicle performance. Laser welding is a kind of manufacturing process to weld these raw materials into the battery cell, battery pack, etc., which is very critical for the whole production process of the power battery.

Comparison of Common Welding Methods of Power Battery
Many packaging technologies are applied to the actual production process of power battery: laser welding, electric resistance welding, ultrasonic welding, cold metal transfer welding technology (CMT), soldering and brazing, vacuum electron beam welding, etc. Appropriate welding methods and optimized process parameters play a significant role in saving the production cost of power battery and ensuring its uniformity, reliability, and safety. Flexible, efficient and precision, laser welding is one kind of non-contact process which can not only meets the performance requirements of the production process of the power battery but great advances the development of new energy power technology.

The following Figure  shows some welding seam pictures with common welding methods, each of which has their advantages and disadvantages in certain application areas. The welding effect of vacuum electron beam welding and laser welding is almost the same since they both are high energy density welding. However, electron beam welding has high requirements for facility and working environment (vacuum), so there is great difficulty in mass production. Currently, it is only used in the production of some special supercapacitor. Laser welding has the advantages of: low welding material loss, no welding flux required, beautiful welding seam, stable performance, easy operation, good welding quality, the high degree of automation and process repeatability, which cannot be matched by other welding methods.
