Selecting the correct nickel strips is crucial for successful spot welding of lithium batteries. Here’s some advice: Thickness: Choose nickel strips that are the appropriate thickness for the battery cells. Thicker strips provide more strength but may require higher welding power.
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.
Different welding processes are used depending on the design and requirements of each battery pack or module. Joints are also made to join the internal anode and cathode foils of battery cells, with ultrasonic welding (UW) being the preferred method for pouch cells.
The findings are applicable to all kinds of battery cell casings. Additionally, the three welding techniques are compared quantitatively in terms of ultimate tensile strength, heat input into a battery cell caused by the welding process, and electrical contact resistance.
A parametric study of the welding of cylindrical Hilumin battery cells to thin sheet connectors was also carried out . The authors investigated the effects of various process parameters such as tip geometry, connector strip material and shape, maximum supply voltage, welding time and force, and the distance between two electrodes.
The bonding interface eliminates metallurgical defects that commonly exist in most fusion welds such as porosity, hot-cracking, and bulk inter-metallic compounds. Therefore, it is often considered the best welding process for li-ion battery applications.
