Fraunhofer FFB and tesa SE
Joint research and development activities for durable and sustainable battery cells

25.04.2023 The Fraunhofer Research Facility Battery Cell FFB in Münster, Germany, and tesa SE (Norderstedt Germany), international manufacturer of adhesive tapes and self-adhesive product solutions, will be working closely together in future. The aim is to develop durable and sustainable battery cells for a wide range of industries.

Fraunhofer FFB and tesa SE sign "Memorandum of Understanding" for future research and development activities.

With the signing of the Memorandum of Understanding on the cooperation, both partners confirm their plans to advance research and development activities for the use of innovative tape applications in battery cell technology. In the future, publicly funded projects are to be applied for in the area of material development, among other things, and the technology transfer between science and industry is to be strengthened. Regular interdisciplinary exchanges between Fraunhofer scientists and tesa engineers are also already planned for next May. A white paper bundling the results from the research and development projects is also to be presented soon.

Advancing materials development

Professor Simon Lux, Institute Director of the Fraunhofer FFB says: "We are very pleased about the signing of the groundbreaking Memorandum of Understanding between tesa SE and the Fraunhofer FFB. It paves the way for mutually beneficial, innovation-rich research and development activities that will help to further advance materials development in the field of battery cell technology in an efficient and sustainable manner."

Frank Kolmorgen, tesa SE's Executive Board member responsible for industry, adds: "We want to play a key role in shaping the future of mobility with innovative and more sustainable product and system solutions. To this end, we are working closely with customers and partners worldwide. The cooperation with Fraunhofer FFB and the associated projects will bring us exciting new approaches and insights that we will incorporate into our work. We are looking forward to the joint results."

Tape applications in practice

In battery cell manufacturing, adhesive tapes help to ensure the stability, durability and safety of the battery cell. In addition to fixing the stack of electrodes in the cell, automotive batteries, for example, require secure electrical insulation in the form of a film that encases the cells or battery modules. Furthermore, adhesive tapes are needed during subsequent assembly into battery systems to ensure the positioning of the cells. Adhesive tapes can also make a decisive contribution to sustainability. When it comes to dismantling complex individual parts after many years and thus recycling them by type, adhesive tapes have enormous advantages over other applications. Battery systems can be opened again without destroying them and then recycled separately.

Innovation transfer and technology transfer

Here, the Fraunhofer FFB offers the opportunity for technological implementation and validation of new production solutions for large-scale industrial applications. To this end, the researchers at the Fraunhofer FFB work closely with tesa to enable direct technology transfer in the sense of applied research. This allows innovations to be tested and validated close to production and innovation cycles to be drastically shortened. Highly qualified technology expert teams are available at the Fraunhofer Research Fabrication Battery Cell FFB facility to provide scientifically sound support for the challenges facing industry in joint innovation and development projects. The signing of the MoU is therefore an important step in paving the way for future mutually beneficial research and development activities.
