Furthermore, the system is available in three additional sizes for medium- and large-scale manufacturing processes for the production of cathode or anode slurries.
The YSTRAL Batt-TDS induces dust-free powders under vacuum in a liquid stream, thus enabling the dispersion of powder particles in milliseconds. The dispersion of polymer binders, conductive carbons, and abrasive active materials is tailored to their specific physical properties and structures within the process.
At the end of last year, the Batt-TDS Navi was initially installed in the "FFB Workspace," a research and testing area of approximately 400 m², where the system was presented to the first users. "There is significant interest from industry and other research institutions, and it is likely that in the future the Batt-TDS Navi will only be idle on rare occasions during its regular operation in the "FFB PreFab," says Marcel Berling, Associate Researcher in the Electrode Manufacturing Group at the Fraunhofer FFB. "For us, the rotor-stator operating principle of ystral scattering technology is particularly interesting in this case, since there is hardly any research in a scientific context on this matter."

At the "FFB PreFab," with approximately 6,800 m² of research space, the ystral mixing and dispersion system is now part of a sample line for small-scale cell production. "We are in close contact with the Fraunhofer FFB team and support the operators on-site with system training, courses, and seminars," says David Manke, Managing Director of ystral.
The research factory focuses on the production of flask and prismatic cells, which are used in applications such as electric vehicles, medical technology, and smart devices. At the "FFB PreFab," industrial companies across the entire cell production value chain have the opportunity to test selected process steps or complete production processes related to materials, production technology, energy and resource efficiency, quality, performance, and costs, and optimize them for their specific needs.
In addition to the YSTRAL Batt-TDS Navi, the YSTRAL system at the "FFB PreFab" also includes handling equipment for processing powdered raw materials. Bags containing hazardous substances, such as NMC, can be safely opened in an insulator, and powdered raw materials can be weighed. The powdered materials are then fed into the Batt-TDS via an attached powder hopper without any contact with the environment. Furthermore, part of the Ystral system is a flexibly expandable control unit, as well as several mobile intermediate vessels with an integrated mixer and a capacity of up to 50 liters.

Within the framework of the Battery Cell Research Manufacturing project in Münster, the YSTRAL Batt-TDS Navi machine, developed by Ystral, is being used. This dispersion system for the production of lithium-ion electrode slurries in programmed quantities of up to 12 liters was specifically developed for R&D purposes and allows the entire slurry mixing process to be completed in just a few minutes.
