Avoid aluminum alloy 6061, which cracks when welded. If this material is already specified and cannot be changed, use a 4047 pre-form as a third material which will introduce a large amount of silicon into the weld, which prevents weld cracking. Lithium polymer batteries
Brass (CuZn37) test samples are used for the quantitative comparison of the welding techniques, as this metal can be processed by all three welding techniques. At the end of the presented work, the suitability of resistance spot, ultrasonic and laser beam welding for connecting battery cells is evaluated.
Cylindrical batteries The key to welding the cylindrical cell type lies in the negative terminal weld, where the battery tab is welded directly to the can as opposed to the separate platform on the positive side. The weld on the negative terminal must not penetrate the can thickness which is typically around 0.015-inch (0.3mm).
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.
For the electrical resistance and temperature rise at the joint, the Cu tab to the Cu busbar weld exhibited the best performance. Al is widely used as a lead-tap material for cathodes in pouch-type LIB cells. Al tab-to-tab joining is required for the parallel connection of the LIB cells.
Each cell type has a different set of welding requirements. Cylindrical batteries The key to welding the cylindrical cell type lies in the negative terminal weld, where the battery tab is welded directly to the can as opposed to the separate platform on the positive side.
