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.
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.
The search was then performed using Uppsala University’s Library database and Google scholar which cover a wide range of articles and sources. Three methods for welding batteries were given in the template, being laser beam-, ultrasonic-, and resistance spot welding.
Micro-TIG is best suited for tab-to-busbar welding for low to high capacity packs. For more information read Battery Welding Solutions Using Laser & Resistance Technologies. Battery pack welding. The right technology for your job depends on factors including materials, part accessibility, throughput, and budget.
4.1.2 Effect on the battery cell Small-scale resistance welding is often the preferred method for joining Li–ion batteries into battery packs. This process ensures strong joints with an almost complete elimination of the heat impact on the joined workpieces during a short time.
The bonding interface eliminates metallurgical defects that commonly exist in most fusion welds such as porosity, hot-cracking, and bulk inter-metallic compounds. Therefore, it is often considered the best welding process for li-ion battery applications.
