In this study, the joint ability of two different joining techniques, namely resistance spot welding and laser welding of nickel weld interfaces and joint microstructure were addressed. Similar materials of nickel joint were used to investigate the parallel connection of tab cells for electric vehicle (EV) battery development.
The lithium-ion batteries (Li-ion) were preferred for energy storage due to its characteristic of high-power density. The voltage and current density of a single battery cell will be inadequate for operation in a battery pack. As a result, a battery pack requires the assembly and connection of numerous battery cells, either in series or parallel.
As a result, a battery pack requires the assembly and connection of numerous battery cells, either in series or parallel. The most common way to connect battery cells will be either in series or parallel form, but this is also the main cause of the degradation of consistency between cells [8, 9].
Today’s battery packs come in a variety of configurations, as shown in Figure 1. Battery packs use several different battery types, including cylindrical, prismatic, ultra-capacitor, and pouch. Materials joining requirements vary depending on the battery’s specific type, size and capacity.
The fitness and purpose of the weld needs to be thoroughly tested, however. In the case of an aluminum battery tab to a nickel plated cold rolled steel battery can the mechanical pull strength is quite strong along the direction of anticipated vibrations.
We know that we can easily join a nickel or steel tab to this material, but both materials possess high resistance. Therefore, ideally, the engineer would choose a more conductive tab material like aluminum or copper – materials that will minimize thermal loss and provide a means to quickly discharge and charge the batteries.
