The Technische Universität Berlin is internationally renowned for its exceptional performance in research. Strong regional, national and international networking partnerships with science and industry are an important aspect in this regard. The section of the university involved in this project – Research Center for Microperipheric Technologies- deals with electronic packaging technologies and micro batteries. The micro energy group of TU Berlin works for more than 17 years in the development of lithium batteries and its integration into products. The main task of TUB in SAFELiMOVE is related to High Throughput Testing (HTT) of SSE-Lithium battery materials combinations fabricated as battery cell arrays on planar substrates based on the microbattery
technology and electronic test interface developed together with Fraunhofer IZM. TU Berlin will use the Jetting and dispense-print technology (Aero Jet, Cyber Jet2, Musashi) for deposition of electrodes and solid-state electrolytes in micro cell arrays. Hence, quick changes in material composition in a programmed variation can be produced on the test cell array like variations in blended electrodes, varying amount of binder, graphite, CNTs and other additives as well as variations in the SSE. The capability of performing several hundred battery tests in parallel with a minimum amount of material will be a key success factor of the SAFELiMOVE project.
