Batteries

The usage of batteries has rapidly increased in recent years with new portable electrical and energy storage devices, as well as electric cars. This increased use of batteries in everyday life needs an increased level of efficiency, which is what fiber lasers provide, particularly as they can weld dissimilar metals. With battery usage only likely to increase, reliable and robust lasers are needed to support this.

Battery applications and uses

There are an extensive number of applications within the battery industry which can be achieved with a fiber laser from SPI. Key attributes of our fiber lasers relating to batteries include the non-contact process and the ability to work with absolute precision across a diverse range of materials.

One such application is the removal of coating materials from battery foils, this is an ablation technique where fine layers of material are removed from the battery foil through a non-contact process, therefore protecting the battery foil.

Fiber lasers can also cut battery foils to the precise dimensions required, this includes even the most complex, awkward and unusual of shapes.

Dissimilar metal welding is another frequently required application, where metals with dissimilar qualities (e.g. aluminium and copper) are welded together. This also works within lithium-ion batteries where welding of dissimilar metals is often required at microscopic levels.

E-mobility is set to be a hot topic in the years to come, especially with the ever-increasing availability of electric cars. Of course, batteries are central to e-mobility and here at SPI Lasers, we can help meet all your e-mobility needs. Our fiber lasers can assist in areas such as cutting of coated foil electrodes, tab welding and bus bar welding of battery packs as well as Hairpin ablation and welding for electric motors. Read our e-mobility section for further details.

SPI Lasers within the battery industry

SPI Laser’s single mode redPOWER Fiber Lasers are able to produce the results that battery manufacturers look for the most in their products, particularly high beam quality and brightness, as well as their ability to achieve defect-free joins at high speeds.

Also with just one investment, manufacturers can buy a tool which is suitable for top-quality ablation, cleaning, cutting, engraving, drilling, marking and welding. Why not contact us to see what SPI Lasers can do for your machines, systems or organisation?
