Fully automatic laser welding robot for energy storage batteries

What is battery laser welding?

Ready To Get Started? Battery Laser Welding for Battery Pack Manufacturing Laser welding is one of the most promising joining technologies for EV batteries and energy storage systems. It provides the speed and precision needed to make the thousands of welds that connect tabs and busbars in battery packs, modules, and cells.

What is lithium ion battery laser welding machine?

To meet this growing demand, SIL has developed the Lithium Ion Battery Laser Welding Machine. This innovative machine enables precise welding of prismatic cells made from materials such as aluminum, aluminum alloy, stainless steel, or OFHC Copper. It is capable of welding components with a thickness ranging from 0.5 mm to 3 mm.

What can a battery & laser welding expert do for You?

Our battery and laser welding experts are involved at every step of the project. They can optimize the laser welding performance for your specific application, support your product design phase from a laser welding perspective, assist in preproduction and testing phases, and build battery modules to test your process.

What types of battery cells can be laser welded?

All types of battery cells can be laser welded, including cylindrical cells, prismatic cells, and pouch cells. Laser welding is being implemented for a wide range of electric battery applications: With more than 6kW of laser power, the welding speed can be scaled to meet short cycle time requirements.

Can a laser welding machine make battery-to-busbar connections?

It can make cell-to-busbar connections for various battery-module and battery-pack designs. With its unique engineering and vision that offers the fastest welding speed for batteries, this machine outperforms other laser welding solutions and has the ability to replace over 10 wire bonding machines with a single unit.

Can a laser weld a battery?

Laser welding can be optimized for minimal heat input. As a result, batteries do not suffer from excessive heating and maintain better mechanical properties. Lasers can weld dissimilar materials with varying fusion temperatures without the need for filler material. Examples include steel-copper, steel-aluminum, aluminum-copper, and steel-nickel.
