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.
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.
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.
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.
Therefore, the study of battery welding technology is of great significance for the improvement of connection performance of lithium batteries, process optimization, and process management strengthening of manufacturing engineering.
