Different methods for joining of lithium batteries with electrical conductors are being used in the industry sector. Due to potential hazards associated with battery welding, it is crucial to employ precise joining parameters and have good process control. We studied resistance spot welding of electrical conductors to lithium batteries. We focused on different energy sources and materials that are currently in use. We conducted a mechanical and metallographic analysis of resistance welds between the electrical conductors and lithium batteries. The findings indicate that the use of direct current energy sources, such as capacitor or inverter-based energy sources, result in higher mechanical strength of the first weld. Despite the substantial surface area and good mechanical strength in welds with insufficient fusion, we have determined that they are inappropriate for dynamic loads due to their low ductility.
