Hello I am in the process of rebuilding an old battery pack for a cordless drill, and have acquired a small spot welder. When I spotweld the batteries, having 0.3 mm thick z-tabs, I experience a lot of sparks flying around, and sometimes burning through a tab, without making any contact to the battery I try to weld it to.
Apply a slow charge to a repaired pack to bring all cells to parity. Pay attention when using an unknown cell brand. Elevated temperature hints to an anomaly. Do not charge a Li-ion battery that has physical damage, has bulged or has dwelled at a voltage of less than 1.5V/cell for some time. Check a repaired pack for self-discharge.

An automotive battery pack for use in electric vehicles consists of a large number of individual battery cells that are structurally held and electrically connected.
The present finding suggests that development of failure criteria for prismatic cells should also pay attention to non-jellyroll structures and laser welding connections. Graphical abstract. Download: Download Although some finite element models related to the laser welding on battery pack were introduced in previous publications [48, 51
If the lithium battery pack is often used in an environment with high humidity, nickel plated steel will easily rust, but pure nickel strips will not. This is also one of the favored advantages of pure nickel strips. Spot welding: During the packing process, the connection between nickel strips and cells are all resistance spot welding
