Introduced in 1995, pouch cells have always presented a unique design, where the battery is enclosed in a soft plastic film instead of a rigid casing like cylindrical and prismatic cells.
In this article, we discuss how they have evolved over the years and where they are headed.
Laser welding is a technology that has applications in a wide variety of industries. It is chosen for its ability to generate high-quality welds at high speed. It is also chosen for precision welds that do no cause damage to delicate components.
Laser marking is the first choice when manufacturers need to improve their traceability capabilities. Fiber laser technology is recognized as the best option when it comes to permanent markings, high-contrast codes, post-process resistance, and ease of integration.
All over the world, automakers and OEMs are using structural adhesives to produce the next generation of cars. For those new to this subject, structural adhesives can seem complex to implement
Ultrasonic welding and laser welding have emerged as prominent technologies for making busbar connections in EV battery modules. While both technologies can be automated and offer the quality and precision needed for battery manufacturing, there are important differences to consider
Lasers are ideal for industrial automation. Not only do they have the potential to increase productivity and repeatability, but they also possess key characteristics that facilitate automation. Examples include remote capabilities, low maintenance, almost no consumables and waste products, and minimal dust.
The battery is the most expensive part in an electric car, so a reliable manufacturing process is important to prevent costly defects. Electric vehicle batteries are also in high demand, which puts pressure on manufacturers to maximize production without compromising quality. As a result, robot automation is almost everywhere during battery manufacturing.
With the rapid growth of EVs in the automotive industry, battery welding has become an important challenge to keep up with demanding production requirements. At Laserax, we have developed a laser welding cell that addresses these challenges.
Laser surface treatments can be used on almost all types of metals, including carbon steel, cast iron, aluminum, molybdenum, and magnesium. They can remove contaminants and coatings (laser cleaning), modify the surface roughness (laser texturing), harden surfaces (laser hardening), and add materials to surfaces to improve surface properties (laser cladding).
Laser ablation occurs when a laser beam removes material from a localized area. Used in various industrial applications, this process can create permanent marks (laser marking), remove contaminants and coatings from surfaces (laser cleaning), modify a part’s roughness (laser texturing), cut through a surface (laser cutting) and much more.
Industrial laser welding of copper is in growing demand. One reason is the electrification of the automotive industry, where various electrical components are made of copper to improve electrical and thermal conductivity.
Lasers and robotics are both used by manufacturers for their speed and precision. It’s natural that these two technologies frequently work hand in hand in production lines to perform laser welding.
