Battery Cell Technology

In the field of battery cell technology, we conduct research along the entire value chain from new materials to production processes and innovative cell architectures. Our technical equipment includes various processing tools, glove boxes and characterization instruments to manufacture and characterize complete battery cells. We accompany our work with techno-economic considerations and cell simulations in order to evaluate the economic efficiency and technological effectiveness of our approaches.

Our core fields of activity are:

Contributions to the continuous further development of lithium-ion battery cell technology

Lithium-ion technology is currently the dominant technology in the realization of traction batteries as well as for batteries in a wide range of applications from industrial applications to consumer electronics. This technology develops incrementally in an evolutionary process. In this context, we investigate e.g. silicon-based anode materials as drop-in replacement technology for lithium-ion battery cells to replace graphite-based anodes or to improve them by adding silicon composite materials.

Battery cells with aqueous electrolytes for stationary energy storage

Batteries with aqueous electrolytes are non-combustible, can be produced with highly available and sustainable materials and are suitable for use in stationary energy storage applications. Various concepts are being developed and evaluated at Fraunhofer ISE. For example, we investigate battery cell chemistries based on sodium or zinc ions and develop complete production processes for these cells.

Batteries with solid electrolytes

In the field of solid electrolytes, we are currently concentrating on the processing of sulfide based materials. We develop manufacturing processes to integrate these materials into battery cells and to realize all-solid-state batteries.

Special architectures for small and micro batteries for sensor technology and IoT applications

Using printing technology, we realize small printed battery cells and develop adaptable cell designs for various applications.

Techno-economic evaluation

On the basis of a detailed calculation tool from photovoltaic research, which we have adapted for battery cell production, we develop cost models for battery cell manufacturing processes and battery cell structures. We look at material availability and evaluate new material manufacturing processes and materials to replace currently critical raw materials.

In addition to our research and development on battery cell technology, we offer our customers a basic processing chain for the production and analysis of battery cells and the materials used in them at our Center for Energy Storage Technologies and Systems:

  • Basic processing chain for the production and characterization of battery cells (coin cells and small pouch cells)
  • Basic processing chain for the synthesis of tailor-made Si/C materials and slurries for Si-based anodes
  • Basic processing chain for the production of sulfidic materials, their further processing into battery cells and characterization
  • Test circuits for cycling small battery cells and measurement systems for electrochemical characterization of new battery chemistries
  • Chemistry laboratories including gloveboxes for the various subject areas
  • Powder processing / slurry and paste production (powder mill, furnaces, three-roll mill, disperser)
  • Various film applicators, dryers
