Which welding methods are used in the production of battery applications?
The compared techniques are resistance spot welding, laser beam welding and ultrasonic welding. The performance was evaluated in terms of numerous factors such as production cost, degree of automation and weld quality. All three methods are tried and proven to function in the production of battery applications.
Do high-volume production requirements affect welding performance in battery assembly?
Moreover, the high-volume production requirements, meaning the high number of joints per module/BP, increase the absolute number of defects. The first part of this study focuses on associating the challenges of welding application in battery assembly with the key performance indicators of the joints.
How are battery cells welded?
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.
What is process optimisation in battery welding?
Process optimisation is by far the most researched area of quality assurance for battery welding applications. Most of the studies have been carried out either as pure experimental investigations to find the process parameters that optimise one or more KPIs of a joint, suppress defects, or validate a process model.
Why is parameter control important in battery cell welding?
Parameter control also allows LBW to adapt to the thickness of the material tabs and can create thin or thick weld nuggets. In battery cell welding it is important to create thin welds due to the relatively thin battery cases and the risk of the weld penetrating the case and thus damaging the core.
What is the manufacturing process of Li-ion battery?
The manufacturing process for the Li-Ion battery can be divided roughly into the five major processes: 1. Mixing, kneading, coating, pressing, and slitting processes of the positive electrode and negative electrode materials. 2. Winding process of the positive electrode, negative electrode, and separator. 3.
