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.
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.
To ensure successful lithium batteries’ spot welding, properly setting up and calibrating your spot welder is essential. Here’s a guide: Power Settings: Adjust the power settings on the spot welder according to the thickness of the nickel strips and the type of battery cells in use.
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.
require a long lifespan connection of a battery pack. Similar to welding time setting, it is recommended to start with the lowest maximum supply voltage stage and current strength setting for trial welding. If the value should then be increased to the higher stage. Additionally, performing multiple-spots welding creating results.
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.
