    The “BEST” project is developing an electrode manufacturing process based on a dry coating process for high-throughput fabrication. The picture shows a dry-coated electrode for experimental cells (diameter 18 mm) with a thickness of approx. 2 mm.

    Electrical energy storage systems (EES) are crucial for the energy transition. The “BEST” project aims to develop an innovative process for the production of dry-processed battery electrodes for zinc-ion batteries. This process aims to significantly increase the efficiency and reproducibility of electrode production and eliminate time-consuming steps. By using sustainable PFAS-free binders in combination with innovative technologies, we aim to achieve cost-efficient and environmentally friendly production. | Duration: 02/2025 - 12/2025

    Working at a glovebox on all-solid-state battery cells.

    In all-solid-state batteries the liquid electrolyte is replaced by a solid non-combustible ion conductor. This prevents thermal runaway and significantly increases the safety of battery cells. It also facilitates the use of lithium metal anodes, which makes higher energy densities and thus significantly higher ranges for electric vehicles possible. | Duration: 10/2019 - 09/2022
