Our competence Center for R&D and Battery Cell Prototyping
The Chem4Batteries laboratory, located in central Berlin, works closely with TU Berlin, Humboldt University, and the Fraunhofer Institute as part of the city’s battery research ecosystem. Next to Fraunhofer IZM, which is renowned for its work in microelectronics, lithium-ion batteries, and silicon wafer production, the Chem4Batteries battery laboratory specializes in material benchmarking and the prototyping of battery cells. This includes electrode preparation, battery cell assembly, and battery cell testing. Our laboratory additionally conducts battery cell teardown and postmortem analysis and has access to nearly all advanced analytical tools. Additionally, it serves as the hub for Chem4Batteries’ High Throughput Research and Development activities.
