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.
Oxy-acetylene welding is the most common method for welding lead. The low melting point of lead means the welder can easily melt the base metal and filler metal with an oxy-acetylene torch to achieve a solid weld. TIG welding is also suitable for welding lead due to the capability of this process to weld at very low amperages.
Battery cells are most often put into modules or packs when produced for electrically driven vehicles. The variable of greatest influence when welding battery packs is the contact resistance between the cell and the connection tab. It is crucial to minimize this variable as much as possible to prevent energy loss in the form of heat generation.
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.
Energy storage solutions play an increasingly important role in modern infrastructure and lead-acid batteries are among the most commonly used in the rechargeable category.
