4. Summary and Outlook Laser welding is a welding method with high energy density and non-contact and accurate heat input control, which can provide reliable weldability for the welding between dissimilar materials in the battery system of electric vehicles.
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.
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.
