The chair "Production Engineering of E-Mobility Components" (PEM) of RWTH Aachen University is involved in the "FoFeBat3" project with the investigation of innovative mini-environment concepts and optimized forming conditions. The multi-stage project "FoFeBat" is part of the large-scale Fraunhofer Research Institution for Battery Cell Production FFB located in Münster, North Rhine-Westphalia, whose setup, technology development and production planning PEM is supporting as an official partner.

Near-series battery production on a large scale

The Fraunhofer FFB, in the creation of which other renowned research institutions are involved beyond the region, is intended to provide an infrastructure with which companies and institutes can test, implement and optimize the near-series production of new batteries on a large scale in the future. This should accelerate the innovation and commercialization process of production technologies for existing and future battery cell formats.

Focus on energy-intensive and immature processes

The third sub-project of "FoFeBat" aims to integrate an intelligent and flexible clean and dry room system into the Fraunhofer FFB production environment. In addition, the research partners are investigating the processes of dry coating, laser separation and cell conditioning with a special focus: While dry coating and cell conditioning represent the most energy-intensive production steps to date alongside the clean and dry room system, laser separation is a cell assembly step with a still high practical deficit in flexibility and adaptability. "FoFeBat3" also aims to demonstrate that the feasibility of implementing new types of energy- and resource-efficient production processes, enclosed in mini-environments, opens up new business areas along the entire value chain of battery production and enables innovation leadership in this area.

Further information is also available on the related project FoFeBat2.
