On the way to CO2-neutral mobility: RosiLiB project pursues the development of lithium-ion batteries with high energy density, reduced costs and high environmental efficiency.
Battery performance and cost are critical factors in the electrification of mobility. To achieve higher range at reduced costs, further development of batteries and battery materials is essential. In the project "RoSiLiB", funded by the German Federal Ministry for Economic Affairs and Energy (BMWi), CUSTOMCELLS® is developing together with the partners: Fraunhofer Institute for Manufacturing Technology and Applied Materials Research IFAM in Dresden, the Institute for Ion Beam Physics and Materials Research at Helmholtz-Zentrum Dresden Rossendorf e.V., E-Lyte Innovations GmbH and NANOVAL GmbH & Co. KG are developing high-energy anode material and lithium-ion batteries based on it. In the "RoSiLiB" project, the innovative nanoporous silicon powder-based anode is being developed based on various factors. This includes the further development of a new low-cost manufacturing route for nanoporous silicon microparticles including environmentally friendly (free of hydrofluoric acid) and well-scalable processes. This leads to the fabrication of anodes with a high silicon content. The developed anode is combined with a commercially available next generation cathode (high nickel content). Thus, battery cells with an energy density of more than 350 Wh/kg or 1,000 Wh/l can be produced. CUSTOMCELLS® will participate in the anode paste development and battery cell production as part of the RoSiLiB project.
