Battery cell production: Laser drying significantly reduces operating costs and required production space
Up until now, battery electrodes have been dried primarily in gas-operated conveyor furnaces. However, a recently developed approach based on diode lasers is noticeably superior to the convective drying process and for the first time makes it possible to produce laser-dried anodes and cathodes in a roll-to-roll process. A white paper by Laserline and staff from the PEM (Production Engineering of E-Mobility Components) group at RWTH Aachen University highlights the advantages of this diode laser-based electrode drying process and outlines the path to more efficient, cost-effective and environmentally friendly battery production.
At the Battery Show 2023 Laserline will present energy-efficient solutions for industrial material processing in the field of electromobility. Key topics include copper welding with blue 3 kW cw diode lasers, brake disc cladding to reduce urban particulate pollution, laser drying processes for economical series manufacturing of lithium-ion batteries, and welding applications for sealing battery casings.
Meeting all specifications for brake dust reduction within Euro 7 with diode-laser-based brake disc claddings
In order to counteract the health hazards posed by particulate matter, the EU has for the first time also included dust from braking systems within the new vehicle emission standard, Euro 7. Diode-laser-clad hard coatings enable reliable compliance with all specifications, reducing brake dust with a maximum particle size of PM10 by up to 90 percent. The series-ready cladding process developed by Laserline enables cost-sensitive mass production for all market segments.
IDEEL Project: Manufacture of laser-dried anodes and LFP cathodes achieved first time in a roll-to-roll process
The IDEEL research project aims to introduce a laser drying process as a more climate-friendly and economical method for the volume production of lithium-ion batteries. Within this context, it has now been possible to produce laser-dried anodes and LFP cathodes in a roll-to-roll process for the first time. The innovative manufacturing process significantly reduces energy consumption in electrode production and at the same time enables the drying speed to be doubled.
Highlights of Laserline’s presence at formnext 2022 include cross-material cladding and additive manufacturing processes through application of blue lasers, and infrared-laser-based hard coatings for wear reduction in brake discs. Those interested can find us at Hall 12, Booth B19.
At EuroBLECH 2022 Laserline will exhibit a broad spectrum of diode-laser-based solutions for industrial volume manufacturing. Key topics at the event will be on hot wire aluminum welding, welding of copper with 3 kW cw blue diode lasers, as well as corrosion and wear-resistant coatings, for example as brake disc claddings to reduce urban particulate emissions.

The IDEEL research project, supported by the German Federal Ministry of Education and Research (BMBF) as part of the Battery 2020 funding program, aims to launch a laser drying process for a more climate-friendly and economical series production of lithium-ion batteries. The results will be incorporated into the Fraunhofer Research Fab Battery Cells (Forschungsfertigung Batteriezelle) in Münster, Germany, which will enable users from both industry and research to test and optimize the series production of new batteries.
Schweisstec 2021: Laserline showcasing its digitalized multi-spot-solutions for laser welding and brazing
Diode laser specialist Laserline will present a new development phase of its Digital Laser Solutions for Industry 4.0 process architectures at the Schweisstec 2021 trade fair (October 26-29, Stuttgart, Germany, hall 7, booth 7307). In the meantime, not only beam sources but also processing optics with multi-spot module can be digitally programmed, controlled and monitored. The optics were developed specifically for joining applications. This enables the optimization of industrial brazing and welding processes, in addition to supporting the full integration of laser systems into a digitalized process control.
Laserline has optimized its portfolio in the high-power blue diode laser segment. In doing so, the company is making important advances in focusing properties. This is because with output powers of up to 800 watts blue lasers will be available with 20 mm-mrad beam quality, while lasers with output powers of up to 1,500 watts will be available with 30 mm-mrad beam quality. These improvements simplify the joining of thin copper contacts as well as welding with scanner optics.
Within a year, Laserline has been able to double the power of blue CW high-power diode lasers with 450 nm wavelength. With the LDMblue 2000-60, a new high-power diode laser is available in the compact 19” rack, offering 2 kW output power at 60 mm mrad beam quality. As a result, when welding non-ferrous metals, especially when joining copper components for the electronics industry, higher process speeds and deeper weldings become possible.
Under the watchword ‘Digital Laser Solutions’, Laserline has expanded its portfolio with hardware and software solutions for the implementation of fully networked Industrie 4.0 process architectures. All Laserline LDF diode lasers are with immediate effect ex works available with OPC UA interfaces and can thus be integrated seamlessly into IoT architectures on an OPC UA basis. Additionally, Laserline offers a retrofit solution for the OPC UA upgrade of existing systems. By the IoT integration of the laser, the switchover to a forward-planning or condition-depended maintenance inter alia is supported.
