The competencies of the individual departments

The researchers at the iwb develop strategies for an efficient production of tomorrow. To this end, the departments and their teams work together with project partners to investigate current issues in a scientific and problem-oriented manner. The work is carried out in the research fields of the institute or at the companies on site.

Department Additive Manufacturing

Additive (generative) manufacturing processes, publicly referred to as „3D printing“ or „rapid prototyping“, are playing a continuously increasing role in production engineering. Today, the term "Additive Manufacturing" refers to all manufacturing processes, in which a component is produced in layers, providing numerous design freedoms.

The Department Additive Manufacturing at the iwb concentrates on the processing of metallic materials. The process portfolio includes selective laser beam melting (LBM), wire and arc additive manufacturing (WAAM), binder jetting and ink jet printing. Various systems for processing polymers, which are primarily used for teaching or for the production of prototypes, complete the equipment. The methodological core competencies of the Department Additive Manufacturing include process development, process simulation on different scales and process monitoring. In addition, the Department Additive Manufacturing possesses expertise in the field of machining post-processing of additively manufactured components through joint research work with the Department Machine Tools.

Head of the Department: Andreas Bachmann


The main research topics of the Department Additive Manufacturing in detail:

  • Additive manufacturing processes
    This research field concentrates on individual additive processes and the underlying physical effects. The focus is on the development of new processes as well as the extension of process understanding of existing processes. In particular, the recording and description of the fundamental cause-effect relationships in additive manufacturing processes are of interest. A sound understanding of processes not only serves to improve the robustness and process reliability of additive manufacturing processes, but also forms the starting point for the development of new processes and derivatives as well as for the qualification of new materials for additive manufacturing.
    Research Field Leader: Andreas Wimmer
  • Process chain and component design
    In this research field, overarching questions arising from the use of additive manufacturing in production systems are investigated. This means that the interactions and interrelationships of the additive manufacturing process with pre- and post-processing steps within the process chain are analyzed. These include, for example, methods for controlling or compensating component distortion along the entire additive process chain or the suitable coordination of Additive Manufacturing and post-processing in order to be able to manufacture components with a high surface quality.

Department Battery Production

Powerful electrochemical energy storage systems are of great importance for applications in electromobility and stationary energy storage. Herefor, the improvement of gravimetric and volumetric energy density as well as the reduction of production costs are decisive. Only a deeper understanding of the processes involved in manufacturing LIB will enable producing improved and more cost-effective battery cells.

Therefore, the research activities of the Department Battery Production focus on the production of innovative battery cells. The core of the work is process development and the optimization of all processes within battery production. From mixing the electrode materials to the first charging and discharging cycles of the cells as well as assembling the battery modules, all steps are carried out in-house at the iwb's research production line. Occupational safety is always in the foreground here. The iwb's industry-related research also ensures that the highest safety standards are maintained along the entire process chain. The cell portfolio comprises various cell types (button cells, pouch cells and hard case cells) with capacities ranging from a few mAh to over 20 Ah. For this purpose, iwb offers industry-oriented plant technology that can be flexibly adapted to the most diverse requirements.

In addition to the various materials of conventional lithium-ion batteries, the group also researches on solid-state batteries and the use of metallic lithium, as well as silicon composite anodes for the next-generation of lithium based battery technology.

Head of the Department: Florian Günter


The main research topics of the department are:

  • Electrode design and fabrication
    The performance of battery cells depends not only on the materials used, but also on the composition and the structure of the electrodes. Each electrode material requires a new design of the manufacturing processes, which is why a deeper understanding of these is necessary. The processes considered within the research group range from powdered active material to the finished electrode and include mixing and dispersing, coating and drying as well as calendering and laser structuring of the electrodes.

    In the research field of electrode design and fabrication, employees are working intensively on new electrode designs (from slurry formulations to electrode structures) and the processing of new electrode materials. On the cathode side, the focus of research is primarily on low-cobalt materials based on NMC and NCA as well as prelithiated manganese-rich high-voltage spinel. For anode materials, research focuses on silicon composites and the prelithiation of anodes.

    In addition to materials research and research on electrode slurries, the iwb also deals with the design of electrode and cell designs. The focus here is on artificially generated electrode structures using mechanical structuring processes and laser structuring, as well as naturally generated structures using different porosities within the electrode layers.

    Research Field Leader: David Schreiner
  • Cell production and quality
    In cell assembly, functioning cells with high capacity and energy density are produced from individual electrodes. The later errors occur along the process chain, the greater the impact of rejects on costs, which is why quality assurance and process stability are of utmost importance for efficient production at high material costs.

    The research field cell production and quality is intensively concerned with cell assembly and the characterization of large-format battery cells. At iwb, research is carried out in the following process steps: electrode cutting (laser cutting and punching), automated stack formation, contacting, packaging, electrolyte filling, sealing and forming. The various influences of the individual process parameters on the finished battery cell are investigated in detail and the parameters are adapted specifically to the materials used and the requirements of the cell. In order to guarantee high productivity, good quality and low costs along the process chain, wb relies on innovative quality assurance methods and data-based process monitoring. Within the individual processes, various inline quality assurance measures ensure compliance with the required specifications. After each process step, the intermediate product also undergoes various quality controls before it is transferred to the next processing process. This ensures a constant, very high quality of the produced cells.
