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.
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.
Lithium batteries are welded using the autogenous welding process, which does not require any filler material. This process ensures that the electrodes are welded together correctly.
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.
When choosing a lithium battery spot welder, consider the amperage output, duty cycle, voltage drop, and price. How does a lithium battery spot welder work?
