How do you Weld a lithium ion battery case?
During lithium-ion battery packing, joining between battery cases and tabs is challenging for manufacturers due to dissimilar materials of the battery case and the tab, as well as their thicknesses. Laser welding, which has proven to produce a good weld with high productivity and low electrical resistance, is introduced to weld these materials.
Can a laser weld a Battery TAB?
Welding of battery tabs at high speed using single laser pulses from a QCW laser is now well established. Dissimilar metal joints between aluminum and steel and even copper and aluminum have now been developed. There are two approaches to achieving sufficient electrical contact in battery connections from laser welding:
What materials can be laser welded to a battery?
Aluminum alloys, typically 3000 series, and pure copper are laser welded to create electrical contact to positive and negative battery terminals. The full range of materials and material combinations used in batteries that are candidates for the new fiber laser welding processes.
Can aluminum tab-to-tab laser welding connect components in lithium-ion batteries?
This study reports aluminum tab-to-tab laser welding for connecting components in lithium-ion batteries. In this study, laser welding was conducted using multiple spiral welding paths.
Does laser welding produce Li-ion batteries?
The bottom line: with the correct fiber laser welding equipment and process, laser welding is proven to consistently produce high quality welds in 3000 series aluminum alloys that have connections within dissimilar metal joints. The production of Li-ion batteries requires multiple welding processes.
Can a laser weld a high power battery?
Although able to weld both thin and thick tab materials, laser welding is particularly well suited to addressing the needs of high power battery welding. The tab material used in the development of high power cells must be able to accommodate the associated higher capacities and power levels.
