The compared techniques are resistance spot welding, laser beam welding and ultrasonic welding. 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.
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.
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.
electrical connectors are required as electrical bridges between battery cells. For most 18650 Li -ion battery cells, either spot or laser welding technique can be used to weld a sheet metal connector with a battery cell. infrastructure cost is lower . However, the quality of the spot welding technique is lower than which of the
For most 18650 Li -ion battery cells, either spot or laser welding technique can be used to weld a sheet metal connector with a battery cell. infrastructure cost is lower . However, the quality of the spot welding technique is lower than which of the as well as electrode material.
The findings are applicable to all kinds of battery cell casings. Additionally, the three welding techniques are compared quantitatively in terms of ultimate tensile strength, heat input into a battery cell caused by the welding process, and electrical contact resistance.
