Fiber Laser Industries: #02 Battery

Fiber lasers are incredibly versatile and capable of many different fiber laser applications, ranging from precision micro-machining operations, to heavy duty industrial processes i.e welding.

Throughout March, our focus will turn to the Battery sector, looking at just how Pulsed and CW fiber lasers can be used within this industry to help speed up manufacturing processes and reduce costs.

In this article, we investigate a number of key manufacturing applications critical to the Battery sector, alternativly you can read all our Battery related content by visiting our core page HERE.

Welding Batteries

Removal of Coating Material from Battery Foils

The manufacture of Lithium-ion batteries is a highly technical process in which cathodes and anodes are manufactured from thin metallic foils that are coated with active materials.

Cathode materials are typically thin aluminum foil in the 0.012-0.015mm range that are coated with a carbon based lithium containing material that increases the thickness to >0.2mm…….

Dissimilar Metal Welding for Lithium-Ion Battery Cells

The first battery was invented many, many years ago, finding its history dating back to 1800, when Italian physicist Alessandro Volta created the first modern day battery. Since that period the battery saw slow growth, simply because there wasn’t such a need for them.

It goes without saying that the last few decades have changed this trend. In fact, it was said that back in 2013, the average household owned at least 24 different electronic devices; all of these containing some form of battery.

And now, with the invention of things such as electric cars, the production and usage of batteries continues to grow rapidly. As most batteries, including lithium-ion batteries, contain different components and metals, dissimilar metal welding plays a huge part in this industry…..

Remote Cutting of Coated Battery Foils

Coated foils are typically used to create batteries which have a huge range of applications in a large variety of industries, from consumer electronics and hand held mobile devices to the rapidly expanding e-mobility sector. These foils are typically made of aluminium or copper with coated are bare areas on both sides. This can be challenging to process as edge quality must be consistent across all areas of the workpiece.

Copper anode and aluminum cathode foils, coated with lithium ion compound demand high cutting speed and near perfect edge quality to replace punch press machines and render components that can be tightly packed without electrical leakage.

E-mobility offers multiple opportunities for fiber lasers.

E-mobility is continually in the headlines and represents one of the great predicted mega trends for the next decade. The rationale is clear – the world needs to break its dependency on fossil fuels and electric vehicles offer the obvious solution. Predictions suggest that by the mid-2030s electric vehicles will be outselling petrol/diesel models. From a manufacturing perspective this is a paradigm shift from combustion engines to electric motors.

Passenger vehicles can be either plug-in hybrid vehicles (PHEV) or battery electric vehicles (BEV) both of which need batteries and electric motors.

The manufacturing of batteries and electric motors must undergo a transformation to match the forecasted growth in volume, accompanied by dramatic improvements in cost, yield and throughput.

Fortunately, today’s industrial lasers are the ideal tools for the manufacture of key components within both batteries and motors; this has stimulated a significant rise in demand particularly for fiber lasers.
