To create a battery pack, it’s necessary to connect the battery cells with conductors. Typically, this connection is achieved through a process called spot welding or spot soldering.
Spot welding involves passing a high current through the conductive material for a brief moment. During this process, the metal surfaces melt and fuse together upon cooling. Spot welding induces localized heating for a short duration, ensuring the integrity of the battery cell’s internal structure is maintained.
