6 FAQs about [Reasons for insufficient welding strength of battery pack]

Are there accessibility issues with battery welding?

This means that, on the one hand, there may be accessibility issues as the testing is performed on already assembled modules or packs, and on the other hand, key performance indicators for battery welding applications, such as electrical and fatigue performance of the joints, are not served.

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.

Why is fusion welding a problem?

The interconnected architecture of the battery pack means that even a single faulty or out-of-spec joint can affect the performance and operation of the entire battery pack. Another challenge, particularly in fusion welding applications, is the joining of non-ferrous dissimilar materials, which promotes the formation of IMCs.

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 quality assurance for battery welding applications?

The quality assurance for battery welding applications is still in its infancy. Commercial solutions exist, but dedicated solutions are based on end-of-line approaches, while online solutions tend to address the generic quality issues of a specific welding process.

Can hilumin battery cells be welded to thin sheet connectors?

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.
