Common battery welding technologys are: ultrasonic welding, resistance spot welding, laser welding, pulse TIG welding. This post combines the application results of the above battery welding technologies in lithium-ion battery systems, and explores the influencing factors. Ultrasonic welding is a solid state battery welding process.
Since the lithium-ion battery system is composed of many unit cells, modules, etc., it involves a lot of battery welding technology. Common battery welding technologys are: ultrasonic welding, resistance spot welding, laser welding, pulse TIG welding.
Since laser welding has the smallest heat-affected zone in all battery welding processes and can be applied to the connection of multi-layer sheets, laser welding is considered to be the most effective battery welding process for lithium batteries. There are many factors affecting the battery welding process of laser welding.
Limiting the application of ultrasonic welding in lithium-ion electronic systems is mainly due to the low welding thickness (<3mm) of this battery welding method and the inability to achieve welding of high-strength material workpieces.
Spot welding is the recommended technique for joining parts of a lithium-ion battery because of several factors: Precision: Precise welds are made possible by the localized heat generation, which doesn’t damage nearby materials. In the process of making batteries, this is vital because too much heat can harm delicate cell components.
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.
