Battery Lab

At the Fraunhofer ILT Battery Lab, researchers focus on optimizing key parameters of batteries, such as capacity, energy density, performance, weight, charging time, charging cycles, chemical composition, and production parameters. The aim is to develop powerful, safe, and cost-effective batteries that meet the specific requirements of various areas of application.

Covering an area of almost 140 square meters, scientists have access to state-of-the-art technologies and a wide range of equipment for laser-based battery production. They are researching new materials and processes for both conventional lithium-ion batteries with liquid electrolytes and future solid-state batteries. Electrical and mechanical test benches enable them to directly evaluate and further optimize the laser processes.

The Battery Lab is equipped with an argon-powered glove box system that integrates vacuum-based PVD coating technology and a high-temperature furnace. This allows researchers to coat air-sensitive solid-state cell materials and then install them in test cells.

Additionally, they are investigating the possible applications of laser technology for cutting and welding battery components in the Battery Lab. The use of UKP lasers enables precise and damage-free processing of electrode foils. The Fraunhofer team connects battery cells to battery modules and modules to battery packs in order to make conventional production processes more efficient.

By establishing its own hydrogen laboratory, the Hydrogen Lab, Fraunhofer ILT has created the ideal conditions for perfecting fuel cells as the core component of hydrogen technology – from the fundamentals to series production. The Hydrogen Lab's wide range of technical equipment opens up a variety of opportunities for seamless interdisciplinary collaboration. For public projects and industrial collaborations, it offers a unique space for achieving synergy effects at the highest scientific and technological level.

Fraunhofer scientists are conducting research in various projects to advance the cost-optimized and demand-oriented series production of fuel cells. They are tapping into technological and economic potential and accelerating the structured rollout in industry and society.

The new Hydrogen Lab covers 300 square meters and offers a wide range of laser-based test facilities for different dimensions and designs. These facilities cover the laser-related manufacturing steps along the process chain for the production of metallic bipolar plates used in fuel cells.

Individual manufacturing steps as well as process chains can be examined and evaluated on systems for structuring with ultrashort pulse lasers, for laser-based coating, and for high-speed welding and cutting. The test benches allow laser-manufactured components to be thoroughly tested for hydrogen tightness and efficiency.
